Enhance Error Handling and Logging Infrastructure

Description

Summary of Work

This pull request introduces a comprehensive error handling and logging system for our file and CDN services. The changes aim to:

1. Standardize error responses across the application
2. Provide more informative and consistent error handling
3. Improve logging and traceability of errors
4. Enhance security by preventing information leakage

Key improvements:

• Added custom FileAccessError for file-related permissions
• Created centralized error response utility
• Implemented consistent error logging mechanism
• Added type-safe error handling in TypeScript
• Improved error message granularity

Changes Made

Error Handling Improvements:

• Introduced FileAccessError class in fileErrorHandler.ts for precise file access errors
• Created ERROR_TYPES enum in error-response.js to standardize error types
• Implemented createErrorResponse and createErrorLog utilities
• Added middleware for handling file-related errors
• Enhanced error logging with timestamp and context

Architectural Changes:

• Separated error handling logic into dedicated modules
• Created a more robust error management strategy
• Improved type safety with TypeScript
• Centralized error response generation

Tests and Verification

Verification Steps:

• Unit tests for FileAccessError and error handling middleware
• Tested error response generation with various error types
• Verified logging functionality
• Checked error response status codes and message formats
• Ensured no sensitive information is leaked in error responses

Test Coverage:

• Added test/fileErrorHandler.test.ts for middleware testing
• Existing test/error-response.test.js validates utility functions
• Manual testing of error scenarios in different contexts
