Global Error Handling and Status Codes

The application employs global error handling to ensure consistent error responses. HTTP status codes are utilized to indicate the nature of errors:

• 404: Resource not found.
• 400: Bad request - when the request is malformed or invalid.
• 409: Conflict - when there is a conflict with the current state of the server (e.g., attempting to create a resource that already exists).
• 500: Server error.

This approach helps maintain a standardized response format and enhances the user experience by providing meaningful error messages and appropriate HTTP status codes.
