There is such a code

$.post(url, function (data) { if (typeof callback == 'function') { callback(data); } }) .done(function (response) { console.log(response); }) .fail(function () { alert("error"); });

The request goes to the controller url = blah blah.json
If the request is successful, everything works fine. It is necessary to process 415 responce In the controller, the following code:

  return new Response(Response::HTTP_UNSUPPORTED_MEDIA_TYPE);

In Route defaults = {"_format"="json"}, requirements = {"_format"="json"} ,

I get the following error in the browser:

Uncaught TypeError: Cannot use 'in' operator for search for 'length' in 415

In general, I overcame the error return new Response('',Response::HTTP_UNSUPPORTED_MEDIA_TYPE);

And how to handle exactly 415 response? so that the error does not fall into the console

  • Uncaught TypeError: Cannot use 'in' operator for search for 'length' in 415 where does this happen? - Grundy

In general, so

  $.ajax(url, { method: 'POST', success: function (data) { }, statusCode: { 415: function (xhr) { } } });

    Try this. return new Response('неподдерживаемый тип данных', 415);
