Enhance Error Handling and CDN Middleware Improvements

Description

Summary of Work

This pull request consolidates multiple feature branches to improve error handling, logging, and CDN-related middleware in our application.

Key improvements:

• Implement centralized error response utility
• Add CDN path sanitization middleware
• Enhance file access error handling
• Improve CDN file retrieval logging

These changes aim to:

• Standardize error handling across the application
• Improve security for CDN file path processing
• Provide more robust logging for file retrieval operations
• Create a more consistent and maintainable error response mechanism

Consolidated feature branches:

• feat-cdn-path-sanitization-middleware
• feature-centralized-error-response-utility
• feature-file-access-error-handling
• feature-implement-cdn-file-retrieval-logging

Changes Made

1. Centralized Error Response Utility

• Created a centralized mechanism for handling and formatting error responses
• Ensures consistent error reporting across different parts of the application

2. CDN Path Sanitization Middleware

• Implemented middleware to sanitize and validate CDN file paths
• Prevents potential security vulnerabilities related to file path traversal
• Adds an additional layer of input validation

3. File Access Error Handling

• Improved error handling for file access operations
• Added more informative and structured error messages
• Implemented robust error catching and logging mechanisms

4. CDN File Retrieval Logging

• Enhanced logging for CDN file retrieval processes
• Added detailed logging for file access attempts
• Includes contextual information to aid in debugging and monitoring

Tests and Verification

Test Coverage:

• Unit tests for error response utility
• Middleware validation tests for CDN path sanitization
• Error handling test cases for various file access scenarios
• Logging verification for CDN file retrieval operations

Verification Steps:

1. Run full test suite to ensure no regression
2. Manual testing of error handling scenarios
3. Verify logging output and format
4. Check middleware path sanitization effectiveness
5. Validate centralized error response formatting
