.Ajax method works on local machine, but not on server

Question

I have an .Ajax method that calls a method on the page behind (does some logic, then calls a WCF service, then returns an object) that looks like this:

$.ajax({
            type: 'POST',
            url: 'MyPage.aspx/TestMethod',
            dataType: "json",
            contentType: "application/json",
            data: "{'Id': '" + Id + "'}",
            success: function (data) {
                $("#randomElement").html(data.d.Foo);
            },
            error: function ((xhr, textStatus, error){
            alert(xhr.statusText);
            alert(textStatus);
            alert(error);

        });

And the page behind:

  [System.Web.Services.WebMethod]
        public static MyObject TestMethod(string Id)
        {
            //Logic removed for readability!

            return MyService.GetStuff(Id);

        }

This works perfectly fine on my local machine, but fails to work when I deploy to my server.

I have determined that the page behind method does not get called (i.e. the error is in calling TestMethod(), not TestMethod() calling the service).

I have also placed an alert before the .ajax method to show me the path of the page I am on just in case it was doing something funny with the uri on the live server, and it comes back as "/MyPage.aspx" as I would expect.

I also changed the "url:" to the full uri to see if that helped and it didn't.

After running fiddler with custom errors off, I get the following error:

{"Message":"Thread was being aborted.","StackTrace":" at System.RuntimeMethodHandle._InvokeMethodFast(IRuntimeMethodInfo method, Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeType typeOwner)\r\n at System.RuntimeMethodHandle.InvokeMethodFast(IRuntimeMethodInfo method, Object target, Object[] arguments, Signature sig, MethodAttributes methodAttributes, RuntimeType typeOwner)\r\n at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks)\r\n at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)\r\n at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary2 parameters)\r\n at System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary2 parameters)\r\n at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.Threading.ThreadAbortException"}

Should the url be MyPage.asmx/TestMethod instead of MyPage.aspx/TestMethod? — John Pick
What response are you getting from the ajax request when it fails on the server? Is it returning a 200, 404, 500, something else? — kendaleiv
@JohnPick No, the call is to an aspx web page behind method, not an asmx web service. — Ben
@kendaleiv I have updated the code in the question to show the error handling I have put in place (found from the internet). The messages that show in the 3 alerts are: "Error", "Error" and "Internal Server Error" in that order. Is there a way to get better error details? — Ben
You can examine what the server is returning for the ajax request with Firebug, Chrome Developer Tools, or Fiddler. — kendaleiv

Your JSON is not valid; you need to use double quotes:

data: '{"Id": "' + Id + '"}',
