Enhance Markets Endpoint Error Handling Middleware

Description

Task

Create error handling middleware for markets endpoint

Acceptance Criteria

• Implement custom error classes for market errors
• Create middleware to handle different error scenarios
• Provide meaningful error responses
• Support logging of errors
• Maintain type safety

Summary of Work

Error Handling Middleware Implementation

Changes Made

• Developed comprehensive error handling for markets endpoint
• Created custom error classes to handle specific market-related error scenarios
• Implemented structured error response middleware
• Added detailed error logging and categorization

Implementation Details

1. Custom Error Classes:

   • MarketError: Base error class for market-related errors
   • InvalidParameterError: Handles invalid input parameters (400 status)
   • ResourceNotFoundError: Manages scenarios where requested resources are not found (404 status)
   • RateLimitError: Handles rate limiting scenarios (429 status)

2. Error Handling Middleware:

   • Captures and processes different types of errors
   • Provides consistent, structured error responses
   • Includes detailed error type, message, and timestamp
   • Logs errors for monitoring and debugging purposes

3. Error Response Structure:

   {
     "error": true,
     "type": "ErrorType",
     "message": "Detailed error description",
     "timestamp": "ISO_TIMESTAMP"
   }

Testing Approach

• Implemented comprehensive unit tests for custom error classes
• Verified error handling for various scenarios
• Ensured correct status codes and error response formats
• Tested both expected and unexpected error conditions

Important Notes

• Error handling is non-intrusive and easily extensible
• Supports future addition of new error types
• Provides clear debugging information without exposing sensitive details

Potential Future Improvements

• Add more granular error types if needed
• Implement additional logging mechanisms
• Create more specific error subclasses

Changes Made

• Created custom error classes for market endpoints
• Implemented error handling middleware
• Added structured error response generation
• Included comprehensive error logging

Tests

• Test InvalidParameterError creation and handling
• Test ResourceNotFoundError status and message
• Test RateLimitError with default and custom messages
• Verify error response structure matches specification
• Ensure unexpected errors are handled gracefully
