angularjs NodeJS server performs POST request, but returns HTTPErrorResponse

  1. In your AngularJS frontend, make sure you are sending the POST request to the correct endpoint on your Node.js server.
  2. Check if there are any CORS (Cross-Origin Resource Sharing) issues. Make sure your Node.js server is configured to allow requests from your AngularJS frontend.
  3. On the Node.js server, ensure that the POST request is being handled properly by the corresponding route or endpoint.
  4. Check for any server-side errors or exceptions that may be causing the HTTPErrorResponse to be returned. Use logging and debugging tools to identify any issues.
  5. Verify that the server is sending the appropriate HTTP status code and response body for the POST request. Use tools like Postman or browser developer tools to inspect the actual server response.
  6. Confirm that the AngularJS frontend is properly handling the HTTPErrorResponse and displaying any error messages to the user as needed.
