Improve Error Handling for Edge Cases

[GautamAnjali569]

Description

Enhance error handling throughout the application, especially for edge cases where the input data might be invalid or the system fails to perform as expected.

Steps to Implement

1. Review the current error handling in the codebase.
2. Add more specific error messages for different failure points (e.g., invalid input data, failed computations).
3. Implement try/catch blocks where appropriate and log errors for debugging purposes.
4. Return user-friendly error messages when an operation fails.

Expected Outcome

Improved user experience and easier debugging, as error messages will be more specific and informative.
