Hi i am trying to call a C# method to return a json but keep getting errors.

$.ajax({
   type: 'POST',
   url: 'http://ift.tt/1rRQVUu',
   dataType: 'json',
   success: function (response) {
       dataset = response.d;
   },
   error: function (response, success, error) {
        alert("Error: " + error);
   }
});

The error i am getting reads as:

Unexpected token <

Previously i had contentType: 'application/json; charset=utf-8', added but that returned a internal server error.

I would like to call json so that i may populate a javascript.datatable.

C# Function:

public string GetReports()
    {
        System.Data.DataSet d;
        d = (System.Data.DataSet)Session["dsHistory"];

        System.Data.DataSet DsNew = new System.Data.DataSet("cdreports");

        System.Data.DataTable table1 = new System.Data.DataTable("reports");
        table1.Columns.Add("id");
        table1.Columns.Add("name");
        table1.Columns.Add("regAndId");
        table1.Columns.Add("type");
        table1.Columns.Add("timeStamp");
        foreach (System.Data.DataRow row in d.Tables["company"].Rows)
        {
            table1.Rows.Add(row["rc_id"], row["companyname"], row["companyregnumber"], "Company", row["rc_timestamp"]);
        }
        foreach (System.Data.DataRow row in d.Tables["director"].Rows)
        {
            table1.Rows.Add(row["rd_id"], row["firstname"] + " " + row["surname"], row["idnumber"], "Director", row["rd_timestamp"]);
        }
        DsNew.Tables.Add(table1);

        //var myObject = DsNew.GetXml();
        //var json = new JavaScriptSerializer().Serialize(myObject);
        string json = JsonConvert.SerializeObject(DsNew, new DataSetConverter());

        return json;
    }
