I think the problem is that you are trying to pass complete JSON objects. You should use values ​​instead of objects. For example, replace:

var subject = document.form1.subject;

with:

var subject = document.form1.subject.value;

Use this, I think, parentheses mismatch -

    $.ajax(
                 {
        type:"get",
        url:"upload_file.php",
        data:{
        "file":file,
        "date":date,
        "author":author,
        "user":user,
        "semester":semester,
        "class":class1,
        "subject":subject
        },
        success:function(result)
               {
        $("#result").html(result);
        }
    );

We had the same error.

Updated to the latest version of jQuery and the problem is resolved.

This one seems to work for some people , saw this solution here too

Hope this helps.

I came across the same error, but my problem was different.

Turns out I was passing a parameter in an ajax call, which was completely absent in my DOM.

In the case of @ZackValentine (or for those reading this in the future), check the value of all the data items that you are going to pass to the ajax call BEFORE the actual call on its own.
