Throwing this out here as a side note. I was getting that error due to the length of my string variables in my HTML string and the website I used to get my ajax called looked like this.

loc = (loc.substr(loc.length - 1, 1) == "/") ? loc + "Default.aspx" : loc;
        $.ajax({
            type: "POST",
            url: loc + "/" + methodName,
            data: "{" + args + "}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: onSuccess,
            error: onFail
        });

It wasn't capable of extracting the .aspx link correctly, so I just hardcoded my webpage instead of using the loc var.
