[Retry-Logic-Chat-Error-Handling]: Handle Chat Errors by giving the user the option to retry

[Castro19]

💡 User Story

As a user, I want to be able to retry failed bot responses and see clear error messages so that I can recover from failures and understand what went wrong.

📖 Description

Currently, when a bot response fails, users have no built-in way to retry the request. Additionally, error messages could be more specific based on the OpenAI API response types. We need to implement retry functionality in the Redux flow and improve error message handling.

Key files involved:

• Client/src/redux/message/messageSlice.ts
• Client/src/components/chat/chatFooter/ChatInput.tsx
• Client/src/redux/message/crudMessage.ts
• server/src/routes/llm.ts
• server/src/helpers/assistants/responseApi.ts

✅ Acceptance Criteria

• Add retry button in ChatInput component when a message fails
• Implement retry action in messageSlice
• Add specific error handling for different OpenAI API error types
• Show appropriate error messages to users based on error type
• Handle edge cases like:
  • Multiple retry attempts
  • Rate limiting
  • Network connectivity issues
  • Timeout errors
• Preserve message input when retry is needed
• Add loading state for retry attempts

📌 Technical Details

1. Redux State Updates:

// Client/src/redux/message/messageSlice.ts
interface MessageState {
  retryableMessages: {
    [messageId: string]: {
      originalMessage: string;
      attempts: number;
      lastError: string;
    }
  }
}

2. New Actions Required:

// Add to messageSlice.ts
export const retryMessage = createAsyncThunk(
  'message/retryMessage',
  async (messageId: string, { getState, dispatch }) => {
    // Implementation
  }
);

3. UI Component Updates:

// Client/src/components/chat/chatFooter/ChatInput.tsx
// Add retry button component and error display

4. Error Mapping:

// New file: Client/src/redux/message/errorMapping.ts
const ERROR_TYPES = {
  RATE_LIMIT: 'rate_limit_error',
  TIMEOUT: 'timeout_error',
  NETWORK: 'network_error',
  // ... other error types
};

📎 Related Issues or Dependencies

• Depends on existing OpenAI API integration
• May require updates to error handling middleware
• Consider rate limiting implementation

🚀 Priority & Story Points

• Priority: High
• Story Points: 5

Additional Notes

1. Error handling should be implemented at multiple levels:

   • Client-side validation
   • Network request handling
   • Server-side error processing
   • OpenAI API error handling

2. Consider implementing a maximum retry limit to prevent infinite retry loops

3. Error messages should be user-friendly but also provide enough detail for debugging when needed

4. The retry mechanism should preserve the entire chat context and thread ID when retrying

5. Consider adding analytics to track retry attempts and success rates

This implementation will improve the user experience by providing clear feedback and recovery options when message delivery fails, while maintaining the existing functionality of the chat system.
