Check for data format mismatches (string vs object)
Validate component schemas
Review data transformation needs
Review Component Configuration
Check all required fields are filled
Verify API keys and credentials
Confirm endpoint URLs are correct
Test component settings individually
Connection Diagnostics

Data Flow Issues
Problem: Data not flowing between components correctly
Solutions:
Check Data Mapping
Verify field mappings between components
Check for missing required fields
Validate data transformations
Test Data Flow
Use playground to test individual components
Check intermediate outputs
Validate data at each step
Debug Mode
Enable debug logging
Check component execution order
Monitor data transformations
Performance Issues
Slow Workflow Execution
Problem: Workflows taking too long to execute
Diagnostic Steps:
Identify Bottlenecks
Check execution times for each component
Monitor resource usage
Identify slowest components
Component Analysis
{ "performance_metrics": { "component_name": "OpenAI GPT-4", "execution_time": 15000, "input_size": 5000, "output_size": 1200, "api_calls": 1 } }Optimization Strategies
Use faster models for simple tasks
Implement caching for repeated queries
Reduce input/output sizes
Consider parallel processing
Workflow Timeouts
Problem: Workflows timing out before completion

Adjust Timeout Settings
{ "timeout_settings": { "default": 30000, "llm_calls": 60000, "file_processing": 120000, "api_requests": 10000 } }Break Down Large Tasks
Split large workflows into smaller chunks
Use async processing where possible
Implement checkpoint/resume functionality
Resource Optimization
Reduce model complexity
Optimize input data size
Use streaming for large responses
Component-Specific Issues
AI Model Issues
Problem: AI model components not working correctly
Solutions:
Model Configuration
{ "model_config": { "model": "gpt-4", "temperature": 0.7, "max_tokens": 1000, "top_p": 1.0, "frequency_penalty": 0, "presence_penalty": 0 } }Input Validation
Check prompt format and length
Validate input parameters
Ensure proper context setup
Output Processing
Handle model response formats
Check for truncated responses
Validate output against expected schema
Data Processing Components
Problem: Data processing components failing
Solutions:
Input Format Validation
Check supported file formats
Validate data structure
Ensure proper encoding (UTF-8)
Processing Limits
Check file size limits (max 100MB)
Validate text length limits
Monitor processing quotas
Error Handling
try: # Process data result = process_data(input_data) except ValidationError as e: # Handle validation errors log_error(f"Validation failed: {e}") except ProcessingError as e: # Handle processing errors log_error(f"Processing failed: {e}")
Integration Components
Problem: Third-party integration components failing
Solutions:
API Credentials
Verify API keys are valid
Check authentication methods
Confirm endpoint URLs
Service Status
Check third-party service status

Validate callback URLs
Workflow States and Execution
Workflow Won't Start
Problem: Workflow fails to initialize or start execution
Solutions:
Validation Checks
Ensure all required components are configured
Check for circular dependencies
Validate workflow structure
Permission Issues
Verify workflow publish status
Check execution permissions
Confirm API access rights
Resource Availability
Check account quotas
Verify service availability
Monitor system resources
Partial Workflow Execution
Problem: Workflow stops partway through execution
Solutions:
Error Handling
Check component error messages
Review execution logs
Identify failing component
Recovery Mechanisms
{ "retry_config": { "max_retries": 3, "retry_delay": 1000, "exponential_backoff": true, "retry_on_errors": ["timeout", "rate_limit"] } }Checkpoint System
