Ajax call. Always return error

Get stacked with ajax call. I'm allways getting error. I've tried to return from server ArrayList because i have some scheme in some my projects. But the result was same. Json is valid. Staus 200 OK and permanent error.

Here is my client-side code

$.ajax({
        type: "POST",
        url: "services.aspx/GetHexString",
        data: "{'strGetParamsString':'LYALYA'}",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(msg) {
            alert(msg.d);
        },
        error: AjaxFailed
    });

Server-side logic:

[WebMethod]
    public static string GetHexString(string strGetParamsString)
    {
        return "HI";
    }

Firebug shows 200 OK status. And the result is {"d":"HI"} http://jsonlint.com/ says that json is valid.

What is wrong?

Add error_reporting(0); to the top of your php page. With the json array that returns if you happen to have an Undefined variable or you have the error_reporting on it will mess up the array data. I don't know all the full details on this but it works for me.

Tried your code here and it works fine. Have you added text to your error callback to display the error?

error: function (jqXHR, textStatus, errorThrown) {
  alert(textStatus);
  alert(errorThrown);
}

To get more information about you error, add parameters to your error callback function. From the jQuery docs:

error(jqXHR, textStatus, errorThrown)

errorThrown will contain some info.
