I am not sure wha is going on here but I am repeatedly receiving this error when trying to use the REST API when saving a form. I make the $.ajax call, wait for the promise to return but at some point the promise gets stuck in the middle and never returns, but instead if I go through enough F10 function in the debugger this is the error I receive. I am at my wits end because I have this working perfectly fine using the same methods on other sites, but this one doesn’t seem to want to cooperate.
var promise1, promise2;
var promise_array = [];
if(vm.receivables) {
promise1 = user.postDealItem(args....).then(function(response) {
vm.model.recId = response.Id;
return response
});
}
if(vm.standard) {
promise2 = user.postDealItem(args...).then(function(response) {
vm.model.stdId = response.Id;
return response
});
}
if(promise1 != null) promise_array.push(promise1);
if(promise2 != null) promise_array.push(promise2);
$.when.apply($,promise_array).done(function(response) {
//never gets to this point
});
The promise never returns even on the few times it reaches a success stage, it just reloads the page. At my wits end over this one, have been dealing with this for the past 2 days and have not gotten any closer to a solution. I am using SP2013 online at my company’s site and have angular integrated with it(although I prefer jQuery promises/$ajax methods)
In fact the answer was an issue with IE11 that appears intermittently where a post request times out between the send and the receive, so when the post returns, it has nowhere to send the data to---no error, no exception, no nothing most times, just a reload of the page...
I tracked it down by watching th network very closely before it sent and stopped it right before it reloaded. It aborted the XMLHTTPRequest and then I started digging...found that you need to set a few other blank functions in the ajax cal like completed and beforeSend and then put timeout: 0...this somehow prevents IE11 from timing out...worked the first attempt after I did this and every attempt after...
IE is the worst browser ever made, it needs to die a quick painful death.
