DataTables警告：表id = employeeTable-Ajax错误。有关此错误的更多信息

Question

我正在使用JQuery ajax选项为DataTables加载数据，这是我的代码，

$("#employeeTable").DataTable({
    "ajax": {

        "url": "/Parameter/GetEmployeeData",
        "type": "GET",
        "processing": true,
        "datatype": "JSON",
        "serverSide": true
    },
    "columns": [
          {
            "data": "ID", "render": function (data) {

                return `<button type="button" onclick="location.href='@Url.Action("Edit", "Parameter")/${data}'" class="btn btn-warning">Edit</button>`
            },

            orderable: false
        },
        { "data": "PARAMETER_ID" },
        { "data": "LoanType.LOAN_TYPE_DESC" },
        { "data": "REPAYMENT_SCORE" },
        { "data": "CREDIT_RISK_GRADE" },
        { "data": "CRIB_STATUS" }
    ]
}).fnDestroy();

当我在VS中运行代码时，此代码工作正常。在IIS服务器中发布我的应用程序之后。发生以下错误。

这是我的参数控制器GetEmployeeData()方法

public JsonResult GetEmployeeData()
{
    var employeeList = cutOffMarks.GetCutoffMarksList().OrderByDescending(x => x.PARAMETER_ID);
    return Json(new { data = employeeList }, JsonRequestBehavior.AllowGet);
}
