The Ajax POST request encounters failure, although it functions properly in the console

The ajax function below is encountering an error message with little information, simply stating "error":

var form = formInfo;
var url = $(formInfo).attr("action");
var data = $(formInfo).serialize();
$.ajax({
            type: "post",
            url: url,
            data: data,
            dataType: "text",
            **cache: false,**
            success: function (r) {
              //do stuff here
            }, error: function (r) {
              //do some logging stuff here
            }
 });

I'm puzzled by the fact that when I manually run the same ajax call in the console, it works without any issues. Additionally, if I debug through the backend code using a breakpoint, the post goes through successfully. Do you have any insights into what might be causing this unexpected error?

EDIT: After further investigation, it appears that the problem stemmed from caching, and setting cache: false resolved the issue. EDIT 2: Another factor contributing to the problem was that window.location was being triggered before the ajax call finished executing, so we moved it to a function called within the success callback.

It's possible that your form hasn't fully loaded when the request is made.

To solve this issue, you can encapsulate your code within a ready function or relocate your JavaScript to the end of the page.

$(document).ready(function () {
    //insert your code here
});
