由于 JSON 响应较大，AJAX 请求失败

Question

I having a problem with the following function:

function get_request(url){
    $.ajax({
        type: 'GET',
        url: url
        success: function(response){
            get_request_success(response)
        },
        fail: function(){
            get_request_fail()
        }
    });

the server is giving a normal 200 response with the response in the body.

this is the response header (irrelevant data is deleted) Content-Type: application/json content-Lenght: 47954 Server: Werkzeug/1.0.0 Python/3.76

if I inspect the browser and I go to network, the data is in the response body. so I think that the Jquery code is too quickly concluding that the request is failing, but I am not sure

errorcode:

{readyState: 4, getResponseHeader: ƒ, getAllResponseHeaders: ƒ, setRequestHeader: ƒ, overrideMimeType: ƒ, …}
ParseError
No conversion from text to application/json

Answer 1

problem was a server side problem. Because the server was a python application that was ussing pandas it was passing NaN (not a number) values into the JSON respond. JS did not understand this ofcourse. solution was found to run a .fillna("") on the dataframe.
