Ajax doesn't send data and doesn't show any alerts

Question

I have a problem with ajax. I asked once about ajax but now my code can't send Data or even show alert. This code don't do anything. Only in web console in Data tab at "laravel-session" after click button to send it's changing data

    $('#saveBtn').on('click', function (e) {
            e.preventDefault();
            alert("test");
            $.ajax({
              url: "/ress/Add",
              method: "POST",
              data: $('#addForm').serialize(),
              dataType: 'text',
              success: function (response) {
                alert("test3");
              }
            });
            alert("test2");
        });

This code shows only alert with (test) and (test2) no (test3) even when in code is error function. I dig whole internet to find solution and still without results. (on submit) or other function doesn't work too. I can answer for any solutions if I tried this or other

It now send correctly But I think It's not open route file, because in route file with that I have to add some data to database

Please check error part of ajax, So that you can get what is the error.

 $('#saveBtn').on('click', function (e) {
        e.preventDefault();
        alert("test");
        $.ajax({
          url: "/ress/Add",
          method: "POST",
          data: $('#addForm').serialize(),
          dataType: 'text',
          success: function (response) {
            alert("test3");
          },
            error: function (err) {
               alert("in error");
           }
        });
        alert("test2");
    });
