What is the current behavior?

getData and getBoundaryData server actions will throw 500 error when the servers that defined in .env (DATA_SOURCE_URL and DATA_SOURCE_BOUNDARY_URL) is unreachable/inactive.

What is the new behavior?

This pull request improves error handling and network robustness in the data and useBoundary modules. The changes include adding more descriptive error messages, handling network connection failures, and ensuring consistent error responses.

Enhancements to error handling:

• hooks/useBoundary.ts: Updated the error message logic to include res.message if available, providing more specific error details when an unexpected status code is encountered.

• lib/data.ts:

  • getData: Added a try-catch block to handle network connection errors gracefully. If a connection fails, it now returns a structured error response with a 500 status code and a descriptive message. Additionally, improved error messaging for non-OK responses by including the response body text.
  • getBoundaryData: Similar to getData, added a try-catch block to handle network errors and return a structured error response with a 500 status code and a descriptive message. Changed the URL construction to use the URL class for better readability and maintainability.
