Improve Error Handling in construct_json_meta to Prevent Panics

[Sophie-Ag00001]

PR Description: Enhanced Error Handling in construct_json_meta

Summary of Changes

This pull request implements graceful error handling for the unwrap call in the construct_json_meta function located in src/api/handler.rs. The changes ensure that potential errors are managed properly, providing meaningful error messages when expected data is missing, rather than causing the application to panic.

Motivation

The motivation behind these changes is to improve the reliability of the application by preventing unexpected crashes due to unhandled errors. By adding error checks and handling scenarios where the data might not be present, we ensure a more robust and user-friendly experience.

Context

Previously, the usage of unwrap in the construct_json_meta function could lead to panics if the underlying data was not valid or available. By implementing these enhancements, we aim to promote stability and maintainability within the API.

Testing Instructions

To test these changes:

1. Review the updated construct_json_meta function in src/api/handler.rs.
2. Invoke the function under various conditions to simulate different error scenarios.
3. Verify that the application provides appropriate error messages instead of panicking.

Known Issues or Limitations

As of now, there are no known issues or limitations associated with these changes. However, further testing may reveal edge cases that need to be addressed in future updates.

Please review and provide feedback on the proposed enhancements to error handling!
