jquery ajax ignores 500 status error

Question

I\'m making some GET requests to an App Engine app, testing in Chrome. Whilst I can see in javascript console that some calls result in a 500 server error, I can\'t seem to

Answer 1

I had a similar problem, I was using jquery's promise functions of .done, .fail, .always, and if I encountered a 500 internal server error then it would not fire any of the functions (done, fail, always, error). very weird.

in the end I added a timeout into the .ajax options, when it hits the timeout it throws an error and also runs the .fail method.

searchify.myAjaxSearchTerms = $.ajax({
                        'url': url,
                        type: "GET",
                        'dataType': 'jsonp',
                        'jsonp': 'json.wrf',
                        'jsonpCallback': searchify.cbFunc,
                        timeout: 4000, //needed for 500 errors - will go to fail block on timeout
                        beforeSend: searchify.beforeSendAutocomplete

                    });
searchify.myAjaxSearchTerms.fail(function(XHR, status, error){
                        searchify.clearForm();
                        searchify.renderWarningForNoQuery('
