剑道网格服务器端过滤并且不工作

我正在使用 Kendo 网格，具有服务器端过滤、排序和分页功能。

这是我初始化网格的代码：

在此代码中，服务器端分页和虚拟滚动正常工作，但过滤和短路不起作用。

在任何请求中，我都会得到这个

请求参数的类型。

[HttpPost]
public JsonResult getGridData([DataSourceRequest] DataSourceRequest request)
{
    var userList = data;
    return Json(userList.ToDataSourceResult(request));
}




  $("#grid").kendoGrid({
