当我运行我的代码时，我收到了一个错误 .

无法加载资源：服务器响应状态为500（内部服务器错误）

我使用的是两个表，一个是Order和OrderDetails，它们之间有关系 .

This is my index javascript code:

<script>
$(document).ready(function () {
$("#ordenTrabajo").DataTable({
 "ajax": {
 "url": "/Home/GetData",
 "type": "GET",
 "datatype": "json"
},
 "columns": [
     { "data": "OrderID" },
     { "data": "OT" },
     { "data": "Cliente" },
     { "data": "Tipo" },
     { "data": "NumParte" },
     { "data": "FechaIni" },
     { "data": "FechaFin" },
    ]
 });
 });
$.fn.dataTable.ext.errMode = 'throw';

This is my Control code:

public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
return View();
}
public JsonResult GetData()
{
 InselDBEntities1 dc = new InselDBEntities1();
 List<Order> orderList = dc.Orders.ToList();
 return Json(orderList, JsonRequestBehavior.AllowGet);
}
}
