Add Error Handling

Overview

Implement comprehensive error handling for the current code to make it robust and resilient to failures while maintaining good user experience.

Steps

1. Error Detection
   • Identify potential failure points and edge cases
   • Find unhandled exceptions and error conditions
   • Detect missing validation and boundary checks
   • Analyze async operations and network calls
2. Error Handling Strategy
   • Implement try-catch blocks where appropriate
   • Add input validation and sanitization
   • Create meaningful error messages and logging
   • Design graceful degradation for non-critical failures
3. Recovery Mechanisms
   • Implement retry logic for transient failures
   • Add fallback options for service unavailability
   • Create circuit breakers for external dependencies
   • Design proper error propagation and handling
4. User Experience
   • Provide clear error messages to users
   • Implement proper error status codes for APIs
   • Add loading states and error boundaries for UI
   • Include helpful suggestions for error resolution

Guardrails

• Never swallow errors silently; handle them meaningfully, or log and rethrow.
• Handle errors at meaningful boundaries instead of wrapping every call in try/catch.
• Do not commit, push, merge, or run destructive commands without explicit user consent.
• Never include secrets or credentials in error messages or logs; flag any exposure instead of printing or committing it.
