How to fix uncaught (in promise) error: Request Failed With Status Code 500?

Published on April 12th, 2022

An uncaught (in promise) error is an error that occurs when a promise is rejected, but no error handler is attached to the promise. This can happen if the promise is created in a scope where there is no catch handler, or if the promise is rejected in a way that is not caught by a catch handler. The most common cause of an uncaught (in promise) error is a failed AJAX request. When an AJAX request fails, the promise is rejected, but there is no way to handle the error, so it remains uncaught.

1. Check the status code of the error and see if it is a 500 error

  1. Open your browser and navigate to the URL that you were trying to access when you encountered the error.
  2. In the address bar, type "status code 500".
  3. If you receive a page that looks like the following, it means that your request failed with a status code of 500. HTTP/1.1 500 Internal Server Error
  4. If the status code that you received is not 500, then there is likely a problem with your web browser or your connection and you will need to troubleshoot it.

2. If it is a 500 error, then check the request headers and see if there is a problem with the headers

1.Check the request headers. 2.If there is a problem with the headers, then fix it. 3.If the header problem is not fixed, then the request may have failed due to a problem with the request.

3. If the headers are fine, then check the request body and see if there is a problem with the body

  1. Verify that the headers are correct
  2. Verify that the request body is correct
  3. If the request body is correct, then fix the uncaught (in promise) error.

4. If the body is fine, then check the response headers and see if there is a problem with the headers

If the body is fine, then check the response headers and see if there is a problem with the headers in order to fix uncaught (in promise) error:

  1. Open the response in a text editor.
  2. Look for the HTTP status code.
  3. If the status code is 500, then there is a problem with the headers. Fix the headers and try again.

5. If the headers are fine, then check the response body and see if there is a problem with the body

  1. Check the headers to make sure that they are okay.
  2. Check the response body to see if there is a problem.
