document provides comprehensive information about the error handling system implemented in Devr.AI, including error codes, response formats, and best practices for handling errors in both backend and frontend components. + +## Overview + +The Devr.AI application implements a robust error handling system with the following features: + +- **Standardized Error Responses**: All API errors follow a consistent JSON format +- **Correlation IDs**: Every request gets a unique correlation ID for tracking +- **Comprehensive Logging**: All errors are logged with context and correlation IDs +- **Retry Logic**: Frontend automatically retries failed requests when appropriate +- **Health Monitoring**: Detailed health checks for all system components + +## Error Response Format + +All API errors return responses in the following standardized format: + +```json +{ + "error": { + "code": "ERROR_CODE", + "message": "Human-readable error message", + "correlation_id": "req_1698765432_abc123def", + "timestamp": 1698765432.123, + "path": "/v1/integrations/123", + "context": { + "field": "email", + "resource_type": "Integration", + "additional_info": "value" + }, + "details": [ + { + "field": "email", + "message": "Invalid email format", + "type": "value_error" + } + ] + } +} +``` + +### Response Fields + +- **code**: Standardized error code (see Error Codes section) +- **message**: Human-readable description of the error +- **correlation_id**: Unique identifier for request tracking +- **timestamp**: Unix timestamp when the error occurred +- **path**: API endpoint where the error occurred +- **context**: Additional context information specific to the error +- **details**: Array of detailed validation errors (for validation failures) + +## Error Codes + +### Client Errors (4xx) + +| Code | HTTP Status | Description | +|------|-------------|-------------| +| `VALIDATION_ERROR` | 400 | Request validation failed | +| `AUTHENTICATION_ERROR` | 401 | Authentication required or failed | +| `AUTHORIZATION_ERROR` | 403 | Insufficient permissions | +| `RESOURCE_NOT_FOUND` | 404 | Requested resource not found | +| `CONFLICT_ERROR` | 409 | Resource conflict (e.g., duplicate creation) | +| `RATE_LIMIT_ERROR` | 429 | Rate limit exceeded | + +### Server Errors (5xx) + +| Code | HTTP Status | Description | +|------|-------------|-------------| +| `INTERNAL_SERVER_ERROR` | 500 | Unexpected server error | +| `DATABASE_ERROR` | 500 | Database operation failed | +| `CONFIGURATION_ERROR` | 500 | Invalid or missing configuration | +| `EXTERNAL_SERVICE_ERROR` | 502 | External service unavailable | +| `SERVICE_UNAVAILABLE` | 503 | Service temporarily unavailable | + +### Integration-Specific Errors + +| Code | HTTP Status | Description | +|------|-------------|-------------| +| `INTEGRATION_NOT_FOUND` | 404 | Integration not found | +| `INTEGRATION_CONFIG_ERROR` | 400 | Invalid integration configuration | +| `GITHUB_API_ERROR` | 502 | GitHub API error | +| `DISCORD_API_ERROR` | 502 | Discord API error | +| `WEAVIATE_ERROR` | 502 | Weaviate database error | +| `SUPABASE_ERROR` | 502 | Supabase error | + +## Backend Error Handling + +### Custom Exception Classes + +The backend uses custom exception classes that extend `BaseAPIException`: + +```python +from app.core.exceptions import ValidationError, ResourceNotFoundError + +# Validation error +raise ValidationError( + "Invalid email format", + field="email", + context={"provided_value": user_input} +) + +# Resource not found +raise ResourceNotFoundError( + "Integration", + resource_id="123", + context={"user_id": "456"} +) +``` + +### Error Handling Middleware + +The `ErrorHandlingMiddleware` automatically: + +- Generates correlation IDs for all requests +- Logs request/response details +- Converts exceptions to standardized error responses +- Adds timing information to response headers + +### Logging + +All errors are logged with the following information: + +```python +logger.error( + f"Database error - {exc.error_code}: {exc.detail}, " + f"Correlation-ID: {correlation_id}, " + f"Context: {exc.context}" +) +``` + +Log files are stored in the `logs/` directory: + +- `app.log`: General application logs +- `error.log`: Error-level logs only +- `access.log`: Request/response logs + +## Frontend Error Handling + +### APIError Class + +The frontend uses a custom `APIError` class for structured error handling: + +```typescript +try { + const integration = await apiClient.getIntegration(id); +} catch (error) { + if (error instanceof APIError) { + console.error(`API Error: ${error.code} - ${error.message}`); + console.error(`Correlation ID: ${error.correlationId}`); + + // Handle specific error types + switch (error.code) { + case 'RESOURCE_NOT_FOUND': + showNotFoundMessage(); + break; + case 'VALIDATION_ERROR': + showValidationErrors(error.context); + break; + default: + showGenericError(); + } + } +} +``` + +### Retry Logic + +The API client automatically retries failed requests with exponential backoff: + +```typescript +const retryConfig = { + attempts: 3, + delay: 1000, // 1 second + backoff: 1.5, + retryCondition: (error) => { + // Retry on network errors and 5xx status codes + return !error.response || + error.response.status >= 500; + } +}; +``` + +### Request Tracking + +All requests include unique request IDs for correlation: + +```typescript +// Request headers +{ + "X-Request-ID": "req_1698765432_abc123def", + "Authorization": "Bearer ...", + "Content-Type": "application/json" +} + +// Response headers +{ + "X-Correlation-ID": "req_1698765432_abc123def", + "X-Process-Time": "0.1234" +} +``` + +## Health Monitoring + +### Health Check Endpoints + +| Endpoint | Description | +|----------|-------------| +| `/v1/health` | Overall system health | +| `/v1/health/weaviate` | Weaviate database health | +| `/v1/health/discord` | Discord bot health | +| `/v1/health/detailed` | Detailed diagnostics (dev only) | + +### Health Response Format + +```json +{ + "status": "healthy", + "timestamp": 1698765432.123, + "environment": "production", + "version": "1.0", + "response_time": 0.1234, + "services": { + "weaviate": { + "name": "weaviate", + "status": "healthy", + "response_time": 0.0856, + "critical": true + }, + "discord_bot": { + "name": "discord_bot", + "status": "healthy", + "critical": false + } + } +} +``` + +### Service Status Values + +- **healthy**: Service is fully operational +- **degraded**: Service is operational but with reduced functionality +- **unhealthy**: Service is not operational + +## Best Practices + +### Backend Development + +1. **Use Appropriate Exception Classes**: + ```python + # Good + raise ValidationError("Invalid email", field="email") + + # Avoid + raise HTTPException(status_code=400, detail="Bad request") + ``` + +2. **Include Context Information**: + ```python + raise ResourceNotFoundError( + "Integration", + resource_id=integration_id, + context={"user_id": user_id, "platform": platform} + ) + ``` + +3. **Log with Correlation IDs**: + ```python + logger.info(f"Processing request - Correlation-ID: {correlation_id}") + ``` + +4. **Use Performance Decorators**: + ```python + @log_performance("create_integration") + async def create_integration(data): + # Function implementation + ``` + +### Frontend Development + +1. **Handle Specific Error Types**: + ```typescript + try { + await apiClient.createIntegration(data); + } catch (error) { + if (error instanceof APIError) { + switch (error.code) { + case 'VALIDATION_ERROR': + handleValidationError(error); + break; + case 'RATE_LIMIT_ERROR': + handleRateLimit(error); + break; + default: + handleGenericError(error); + } + } + } + ``` + +2. **Provide User-Friendly Messages**: + ```typescript + const getErrorMessage = (error: APIError): string => { + switch (error.code) { + case 'NETWORK_ERROR': + return 'Please check your internet connection and try again.'; + case 'SERVICE_UNAVAILABLE': + return 'The service is temporarily unavailable. Please try again later.'; + default: + return error.message; + } + }; + ``` + +3. **Use Health Checks**: + ```typescript + const checkBackendHealth = async (): Promise => { + try { + const health = await apiClient.healthCheck(); + return health.status === 'healthy' || health.status === 'degraded'; + } catch { + return false; + } + }; + ``` + +## Configuration + +### Environment Variables + +Error handling behavior can be configured through environment variables: + +```bash +# Logging configuration +LOG_LEVEL=INFO +ENVIRONMENT=production + +# Timeout settings +EXTERNAL_API_TIMEOUT=30 +HEALTH_CHECK_TIMEOUT=5 + +# Rate limiting +RATE_LIMIT_PER_MINUTE=60 +``` + +### Development vs Production + +The error handling system adapts based on the environment: + +**Development Mode**: +- Detailed error information in responses +- Debug logs enabled +- API documentation endpoints available +- Detailed health check endpoint accessible + +**Production Mode**: +- Minimal error information exposed +- Error details logged but not returned to clients +- Enhanced security and performance optimizations +- Detailed diagnostics disabled + +## Monitoring and Alerting + +### Log Analysis + +Use the correlation IDs to trace requests across the system: + +```bash +# Find all logs for a specific request +grep "req_1698765432_abc123def" logs/*.log + +# Find all errors in the last hour +grep "ERROR" logs/error.log | tail -n 100 +``` + +### Metrics to Monitor + +1. **Error Rates**: Track 4xx and 5xx response rates +2. **Response Times**: Monitor API response times +3. **Health Check Status**: Alert on service degradation +4. **External Service Errors**: Monitor third-party API failures + +### Alerting Rules + +Set up alerts for: + +- Error rate > 5% over 5 minutes +- Response time > 2 seconds for 95th percentile +- Critical service health check failures +- Correlation ID gaps (indicating request tracking issues) + +## Troubleshooting + +### Common Issues + +1. **Missing Correlation IDs**: Check that middleware is properly configured +2. **Inconsistent Error Format**: Ensure all endpoints use custom exception classes +3. **Retry Loops**: Verify retry conditions don't retry non-retryable errors +4. **Log Volume**: Adjust log levels in production to manage disk usage + +### Debugging Steps + +1. **Find the correlation ID** from the error response +2. **Search logs** for all entries with that correlation ID +3. **Trace the request flow** through the system +4. **Check service health** endpoints for component status +5. **Review error context** for additional debugging information + +## Updates and Maintenance + +This error handling system should be regularly reviewed and updated: + +1. **Add new error codes** as new features are developed +2. **Update documentation** when error handling patterns change +3. **Review and analyze** error patterns from production logs +4. **Test error scenarios** as part of the development process \ No newline at end of file diff --git a/frontend/src/App.tsx b/frontend/src/App.tsx index 803f9f5..9f70aa6 100644 --- a/frontend/src/App.tsx +++ b/frontend/src/App.tsx @@ -47,7 +47,7 @@ function App() { supabase.auth.getSession().then(({ data, error }) => { if (error) { toast.error('User Login Failed');
