Ajax call returning status code 0 for a 404 Not Found

IamtheWalrus

I have a webpage that calls a rest endpoint using Ajax. I want to print out the http status code when my rest call errors. When the rest endpoint returns a 500, I can see 500 being printed. But when the call returns a 404, then the value 0 is printed. thrownError is blank.

I'm new to Javascript but can anyone tell me why 0 would be printed? It's only for 404s. I've tested 5xx and they are all fine.

$.ajax({
    type: 'GET',
    url: 'mysite.com',
    crossDomain: true
    success: function (data) {
      console.log(data);
    },
    error: function (xhr, ajaxOptions, thrownError) {
      console.log(xhr.status);
    },
  });

Are you shutting down the server when you try the call? 0 can mean connection refused too

Also when the ajax call has been aborted due to browser refresh or similar?

Basically when there's an error in the call

Have you checked your console to see the error? Chrome dev tools have a network tab, and a console that can give more info

Do you have a link to the endpoint you are trying to hit or is it your own backend api?
You can always try a get request using postman to make sure that the url is correct and returning data.

You can use this endpoint to test your application it just returns weather information.
