# Browser Automation Debugging Guide
This guide explains how to use the enhanced debugging features to troubleshoot browser automation issues in the LiveKit Chrome Agent.
## Overview
The enhanced debugging system provides comprehensive logging and troubleshooting tools to help identify and resolve issues when browser actions (like "click login button") are not being executed despite selectors being found correctly.
## Enhanced Features
### 1. Enhanced Selector Logging
The system now provides detailed logging for every step of selector discovery and execution:
- **🔍 SELECTOR SEARCH**: Shows what element is being searched for
- **📊 Found Elements**: Lists all interactive elements found on the page
- **🎯 Matching Elements**: Shows which elements match the search criteria
- **🚀 EXECUTING CLICK**: Indicates when an action is being attempted
- **✅ SUCCESS/❌ FAILURE**: Clear indication of action results
### 2. Browser Connection Validation
Use `validate_browser_connection()` to check:
- MCP server connectivity
- Browser responsiveness
- Page accessibility
- Current URL and page title
### 3. Step-by-Step Command Debugging
Use `debug_voice_command()` to analyze:
- How commands are parsed
- Which selectors are generated
- Why actions succeed or fail
- Detailed execution flow
## Using the Debugging Tools
### In LiveKit Agent
When connected to the LiveKit agent, you can use these voice commands:
```
"debug voice command 'click login button'"
"validate browser connection"
"test selectors 'button.login, #login-btn, .signin'"
"capture browser state"
"get debug summary"
```
### Standalone Testing
Run the test scripts to diagnose issues:
```bash
# Test enhanced logging features
python test_enhanced_logging.py
# Test specific login button scenario
python test_login_button_click.py

# Dynamic Form Filling System
## Overview
The LiveKit agent now features an advanced dynamic form filling system that automatically discovers and fills web forms based on user voice commands. This system is designed to be robust, adaptive, and never relies on hardcoded selectors.
## Key Features
### 🔄 Dynamic Discovery
- **Real-time element discovery** using MCP tools (`chrome_get_interactive_elements`, `chrome_get_content_web_form`)
- **No hardcoded selectors** - all form elements are discovered dynamically
- **Adaptive to different websites** - works across various web platforms
### 🔁 Retry Mechanism
- **Automatic retry** when fields are not found on first attempt
- **Multiple discovery strategies** with increasing flexibility
- **Fallback methods** for challenging form structures
### 🗣️ Natural Language Processing
- **Intelligent field mapping** from natural language to form elements
- **Voice command processing** for hands-free form filling
- **Flexible matching** that understands field variations
## How It Works
### 1. Voice Command Processing
When a user says something like:
- "fill email with john@example.com"
- "enter password secret123"
- "type hello in search box"
The system processes these commands through multiple stages:
```python
# Voice command is parsed to extract field name and value
field_name = "email"
value = "john@example.com"
# Dynamic discovery is triggered
result = await client.fill_field_by_name(field_name, value)
```
### 2. Dynamic Discovery Process
The system follows a multi-step discovery process:
#### Step 1: Cached Fields Check
- First checks if the field is already in the cache
- Uses previously discovered selectors for speed
#### Step 2: Dynamic MCP Discovery
- Uses `chrome_get_interactive_elements` to get fresh form elements
- Analyzes element attributes (name, id, placeholder, aria-label, etc.)
- Matches field descriptions to actual form elements
#### Step 3: Enhanced Detection with Retry
- If initial discovery fails, retries with more flexible matching
- Each retry attempt becomes more permissive in matching criteria
- Up to 3 retry attempts with different strategies
#### Step 4: Content Analysis
- As a final fallback, analyzes page content
- Generates intelligent selectors based on field name patterns
- Tests generated selectors for validity
### 3. Field Matching Algorithm
The system uses sophisticated field matching that considers:
```python
def _is_field_match(element, field_name):
# Check multiple attributes
attributes_to_check = [
"name", "id", "placeholder",
"aria-label", "class", "type"
]
# Field name variations
variations = [
field_name,
field_name.replace(" ", ""),
field_name.replace("_", ""),
# ... more variations
]
# Special type handling
if field_name in ["email", "mail"] and type == "email":
return True
# ... more type-specific logic
```
## Usage Examples
### Basic Voice Commands
```
User: "fill email with john@example.com"
Agent: ✓ Filled 'email' field using dynamic discovery
User: "enter password secret123"
Agent: ✓ Filled 'password' field using cached data
User: "type hello world in search box"
Agent: ✓ Filled 'search' field using enhanced detection
```
### Programmatic Usage
```python
# Direct field filling
result = await client.fill_field_by_name("email", "user@example.com")
# Voice command processing
result = await client.execute_voice_command("fill search with python")
# Pure dynamic discovery (no cache)
result = await client._discover_form_fields_dynamically("username", "john_doe")
```
## API Reference
### Main Methods
#### `fill_field_by_name(field_name: str, value: str) -> str`
Main method for filling form fields with dynamic discovery.
#### `_discover_form_fields_dynamically(field_name: str, value: str) -> dict`
Pure dynamic discovery using MCP tools without cache.
#### `_enhanced_field_detection_with_retry(field_name: str, value: str, max_retries: int) -> dict`
Enhanced detection with configurable retry mechanism.
#### `_analyze_page_content_for_field(field_name: str, value: str) -> dict`
Content analysis fallback method.
### Helper Methods
#### `_is_field_match(element: dict, field_name: str) -> bool`
Determines if an element matches the requested field name.
#### `_extract_best_selector(element: dict) -> str`
Extracts the most reliable CSS selector for an element.
#### `_is_flexible_field_match(element: dict, field_name: str, attempt: int) -> bool`
Flexible matching that becomes more permissive with each retry.
## Configuration
### MCP Tools Required
- `chrome_get_interactive_elements`
- `chrome_get_content_web_form`
- `chrome_get_web_content`
- `chrome_fill_or_select`
- `chrome_click_element`
### Retry Settings
```python
max_retries = 3 # Number of retry attempts
retry_delay = 1 # Seconds between retries
```
## Error Handling
The system provides comprehensive error handling:
1. **Graceful degradation** - falls back to simpler methods if advanced ones fail
2. **Detailed logging** - logs all discovery attempts for debugging
3. **User feedback** - provides clear messages about what was attempted
4. **Exception safety** - catches and handles all exceptions gracefully
## Testing
Run the test suite to verify functionality:
```bash
python test_dynamic_form_filling.py
```
This will test:

# Enhanced Field Detection and Filling Workflow
## Overview
This implementation provides an advanced workflow for LiveKit agents to handle missing webpage fields using MCP (Model Context Protocol) for automatic field detection and filling. When a field cannot be found using standard methods, the system automatically employs multiple detection strategies and executes specified actions after successful field population.
## Key Features
### 1. Multi-Strategy Field Detection
The workflow employs five detection strategies in order of preference:
1. **Cached Fields** (Confidence: 0.9)
- Uses pre-detected and cached field information
- Fastest and most reliable method
- Automatically refreshes cache if empty
2. **Enhanced Detection** (Confidence: 0.8)
- Uses intelligent selector generation based on field names
- Supports multiple field name variations and patterns
- Handles common field types (email, password, username, etc.)
3. **Label Analysis** (Confidence: 0.7)
- Analyzes HTML labels and their associations with form fields
- Supports `for` attribute relationships
- Context-aware field matching
4. **Content Analysis** (Confidence: 0.6)
- Analyzes page content for field-related keywords
- Matches form elements based on proximity to keywords
- Handles dynamic content and non-standard field naming
5. **Fallback Patterns** (Confidence: 0.3)
- Last resort using common CSS selectors
- Targets any visible input fields
- Provides basic functionality when all else fails
### 2. Automatic Action Execution
After successful field filling, the workflow can execute a series of actions:
- **submit**: Submit a form (with optional form selector)
- **click**: Click on any element using CSS selector
- **navigate**: Navigate to a new URL
- **wait**: Pause execution for specified time
- **keyboard**: Send keyboard input (Enter, Tab, etc.)
### 3. Comprehensive Error Handling
- Detailed error reporting for each detection strategy
- Graceful fallback between strategies
- Action-level error handling with optional/required flags
- Execution time tracking and performance metrics
## Implementation Details

## Technical Implementation Details
### Dynamic Discovery Process
1. **MCP Tool Integration**:
- Uses `chrome_get_interactive_elements` to get real-time form elements
- Uses `chrome_get_content_web_form` for form-specific content analysis
- Never relies on hardcoded selectors
2. **Retry Mechanism**:
- 3-tier retry system with increasing flexibility
- Each attempt uses different matching criteria
- Graceful fallback to content analysis
3. **Natural Language Processing**:
- Intelligent mapping of voice commands to form fields
- Handles variations like "email", "mail", "e-mail"
- Type-specific matching (email fields, password fields, etc.)
### Field Matching Algorithm
```python
# Multi-attribute matching
attributes_checked = [
"name", "id", "placeholder",
"aria-label", "class", "type", "textContent"
]
# Field name variations
variations = [
original_name,
name_without_spaces,
name_without_underscores,
name_with_hyphens
]
# Special type handling
type_specific_matching = {
"email": ["email", "mail"],
"password": ["password", "pass"],
"search": ["search", "query"],
"phone": ["phone", "tel"]
}
```
## Benefits of the New System
### 1. Robustness
- **No hardcoded selectors** - eliminates brittle dependencies
- **Automatic retry** - handles dynamic content and loading delays
- **Multiple strategies** - fallback methods ensure high success rate
### 2. Adaptability
- **Works across websites** - adapts to different form structures

### 3. User Experience
- **Natural voice commands** - users can speak naturally about form fields
- **Reliable operation** - consistent behavior across different sites
- **Clear feedback** - detailed status messages about what's happening
### 4. Maintainability
- **Self-discovering** - no need to maintain selector databases
- **Extensible design** - easy to add new discovery strategies
- **Comprehensive logging** - detailed debugging information
## Voice Command Examples
The system now handles these natural language commands:
```
"fill email with john@example.com"
"enter password secret123"
"type hello world in search box"
"add user name John Smith"
"fill in the email field with test@example.com"
"search for python programming"
"enter phone number 1234567890"
```

# Real-Time Form Discovery System
## Overview
The LiveKit agent now features a **REAL-TIME ONLY** form discovery system that **NEVER uses cached selectors**. Every form field discovery is performed live using MCP tools, ensuring the most current and accurate form element detection.
## Key Principles
### 🚫 NO CACHE POLICY
- **Zero cached selectors** - every request gets fresh selectors
- **Real-time discovery only** - uses MCP tools on every call
- **No hardcoded selectors** - all elements discovered dynamically
- **Fresh page analysis** - adapts to dynamic content changes
### 🔄 Real-Time MCP Tools
- **chrome_get_interactive_elements** - Gets current form elements
- **chrome_get_content_web_form** - Analyzes form structure
- **chrome_get_web_content** - Content analysis for field discovery
- **Live selector testing** - Validates selectors before use
## How Real-Time Discovery Works
### 1. Voice Command Processing
When a user says: `"fill email with john@example.com"`
```python
# NO cache lookup - goes straight to real-time discovery
field_name = "email"
value = "john@example.com"
# Step 1: Real-time MCP discovery
discovery_result = await client._discover_form_fields_dynamically(field_name, value)
# Step 2: Enhanced detection with retry (if needed)
enhanced_result = await client._enhanced_field_detection_with_retry(field_name, value)
# Step 3: Direct MCP element search (final fallback)
direct_result = await client._direct_mcp_element_search(field_name, value)
```
### 2. Real-Time Discovery Process
#### Strategy 1: Interactive Elements Discovery
```python
# Get ALL current interactive elements
interactive_result = await client._call_mcp_tool("chrome_get_interactive_elements", {
"types": ["input", "textarea", "select"]
})
# Match field name to current elements
for element in elements:
if client._is_field_match(element, field_name):
selector = client._extract_best_selector(element)
# Try to fill immediately with fresh selector
```
#### Strategy 2: Form Content Analysis
```python
# Get current form structure
form_result = await client._call_mcp_tool("chrome_get_content_web_form", {})
# Parse form content for field patterns
selector = client._parse_form_content_for_field(form_content, field_name)
# Test and use selector immediately
```
#### Strategy 3: Direct Element Search
```python
# Exhaustive search through ALL elements
all_elements = await client._call_mcp_tool("chrome_get_interactive_elements", {})
# Very flexible matching for any possible match
for element in all_elements:
if client._is_very_flexible_match(element, field_name):
# Generate and test selector immediately
```
### 3. Real-Time Selector Generation
The system generates selectors in real-time based on current element attributes:
```python
def _extract_best_selector(element):
attrs = element.get("attributes", {})
# Priority order for reliability
if attrs.get("id"):
return f"#{attrs['id']}"
if attrs.get("name"):
return f"input[name='{attrs['name']}']"
if attrs.get("type") and attrs.get("name"):
return f"input[type='{attrs['type']}'][name='{attrs['name']}']"
# ... more patterns
```
## API Reference
### Real-Time Functions
#### `fill_field_by_name(field_name: str, value: str) -> str`
**NOW REAL-TIME ONLY** - No cache, fresh discovery every call.
#### `fill_field_realtime_only(field_name: str, value: str) -> str`
**Guaranteed real-time** - Explicit real-time discovery function.
#### `get_realtime_form_fields() -> str`
**Live form discovery** - Gets current form fields using only MCP tools.
#### `_discover_form_fields_dynamically(field_name: str, value: str) -> dict`
**Pure real-time discovery** - Uses chrome_get_interactive_elements and chrome_get_content_web_form.
#### `_direct_mcp_element_search(field_name: str, value: str) -> dict`
**Exhaustive real-time search** - Final fallback using comprehensive MCP element search.
### Real-Time Matching Algorithms
#### `_is_field_match(element: dict, field_name: str) -> bool`
Standard real-time field matching using current element attributes.
#### `_is_very_flexible_match(element: dict, field_name: str) -> bool`
Very flexible real-time matching for challenging cases.
#### `_generate_common_selectors(field_name: str) -> list`
Generates common CSS selectors based on field name patterns.
## Usage Examples
### Voice Commands (All Real-Time)
```
User: "fill email with john@example.com"
Agent: [Uses chrome_get_interactive_elements] ✓ Filled 'email' field using real-time discovery
User: "enter password secret123"
Agent: [Uses chrome_get_content_web_form] ✓ Filled 'password' field using form content analysis
User: "type hello in search box"
Agent: [Uses direct MCP search] ✓ Filled 'search' field using exhaustive element search
```
### Programmatic Usage
```python
# All these functions use ONLY real-time discovery
result = await client.fill_field_by_name("email", "user@example.com")
result = await client.fill_field_realtime_only("search", "python")
result = await client._discover_form_fields_dynamically("username", "john_doe")
```
## Real-Time Discovery Strategies
### 1. Interactive Elements Strategy
- Uses `chrome_get_interactive_elements` to get current form elements

### Smart Element Discovery
```python
# Real-time element discovery (no cache)
async def _smart_click_mcp(self, element_description: str):
# 1. Get interactive elements using MCP
interactive_result = await self._call_mcp_tool("chrome_get_interactive_elements")
# 2. Match elements by description
for element in elements:
if self._element_matches_description(element, element_description):
# 3. Extract best selector and click
selector = self._extract_best_selector(element)
return await self._call_mcp_tool("chrome_click_element", {"selector": selector})
```
### Intelligent Form Filling
```python
# Enhanced field detection with multiple strategies
async def fill_field_by_name(self, field_name: str, value: str):
# 1. Try cached fields (fastest)
# 2. Enhanced detection with intelligent selectors
# 3. Label analysis (context-based)
# 4. Content analysis (page text analysis)
# 5. Fallback patterns (last resort)
```

# QuBeCare Login Form Troubleshooting Guide
## Issue: LiveKit Agent Not Filling QuBeCare Login Form
### Potential Causes and Solutions
#### 1. **Page Loading Issues**
- **Problem**: Form elements not loaded when agent tries to fill them
- **Solution**:
- Ensure page is fully loaded before attempting form filling
- Add delays after navigation: `await asyncio.sleep(3)`
- Check page load status with JavaScript
#### 2. **Dynamic Form Elements**
- **Problem**: QuBeCare uses React/Vue.js with dynamically generated form elements
- **Solution**:
- Use enhanced form detection with JavaScript execution
- Wait for elements to appear in DOM
- Use MutationObserver to detect when forms are ready
#### 3. **Shadow DOM or iFrames**
- **Problem**: Login form is inside shadow DOM or iframe
- **Solution**:
- Check for iframe elements: `document.querySelectorAll('iframe')`
- Switch to iframe context before form filling
- Handle shadow DOM with special selectors
#### 4. **CSRF Protection or Security Measures**
- **Problem**: Site blocks automated form filling
- **Solution**:
- Simulate human-like interactions
- Add random delays between actions
- Use proper user agent and headers
#### 5. **Incorrect Selectors**
- **Problem**: Form field selectors have changed or are non-standard
- **Solution**:
- Use the enhanced form detection method
- Try multiple selector strategies
- Inspect actual DOM structure
### Debugging Steps
#### Step 1: Run the Debug Script
```bash
cd agent-livekit
python debug_form_detection.py
```
#### Step 2: Check Agent Logs
Look for these log messages:
- "Auto-detecting all input fields on current page..."
- "Enhanced detection found X elements"
- "Filling field 'selector' with value 'value'"
#### Step 3: Manual Testing
1. Navigate to https://app.qubecare.ai/provider/login
2. Use agent command: `get_form_fields`
3. If no fields found, try: `refresh_input_fields`
4. Use the new specialized command: `fill_qubecare_login email@example.com password123`
#### Step 4: Browser Developer Tools
1. Open browser dev tools (F12)
2. Go to Console tab
3. Run: `document.querySelectorAll('input, textarea, select')`
4. Check if elements are visible and accessible
### Enhanced Commands Available
#### New QuBeCare-Specific Command
```
fill_qubecare_login email@example.com your_password
```
#### Enhanced Form Detection
```
get_form_fields # Now includes JavaScript-based detection
refresh_input_fields # Manually refresh field cache
```
#### Debug Commands
```
navigate_to_url https://app.qubecare.ai/provider/login
get_form_fields
fill_qubecare_login your_email@domain.com your_password
submit_form
```
### Common Issues and Fixes
#### Issue: "No form fields found"
**Fix**:
1. Wait longer for page load
2. Check if page requires login or has redirects
3. Verify URL is correct and accessible
#### Issue: "Error filling form field"
**Fix**:
1. Check if field is visible and enabled
2. Try clicking field first to focus it
3. Use different selector strategy
#### Issue: Form fills but doesn't submit
**Fix**:
1. Use `submit_form` command after filling
2. Try pressing Enter key on form
3. Look for submit button and click it
### Technical Implementation Details
The enhanced form detection now:
1. Uses multiple detection strategies
2. Executes JavaScript to find hidden/dynamic elements
3. Provides detailed field information including visibility
4. Identifies login-specific fields automatically
5. Handles modern web application patterns
### Next Steps if Issues Persist
1. **Check Network Connectivity**: Ensure agent can reach QuBeCare servers
2. **Verify Credentials**: Test login manually in browser
3. **Update Selectors**: QuBeCare may have updated their form structure
4. **Check for Captcha**: Some login forms require human verification
5. **Review Browser Profile**: Ensure correct browser profile is being used
### Contact Support
If the issue persists after trying these solutions:
1. Provide debug script output
2. Share agent logs
3. Include browser developer tools console output
4. Specify exact error messages received
