Object reference not set to an instance of an object when searching

Hello,

I have a DataGrid that correctly displays the data, however, when performing a search, an exception is thrown: "Object reference not set to an instance of an object."

From the stack trace, it appears that the problem is something to do with the column type?

   at Syncfusion.EJ2.Base.QueryableOperation.GetColumnType[T](IQueryable`1 dataSource, String filterString, Type type)
   at Syncfusion.EJ2.Base.QueryableOperation.PerformSearching[T](IQueryable`1 dataSource, List`1 searchFilter)
   at Syncfusion.EJ2.Base.DataOperations.PerformSearching[T](IEnumerable`1 dataSource, List`1 searchFilter)
   at MyPortal.Services.UtilityService.PerformDataOperations[T](IEnumerable`1 dataSource, DataManagerRequest dm) in C:\Users\rowan\RiderProjects\MyPortal\MyPortal\Services\UtilityService.cs:line 22
   at MyPortal.Controllers.Api.MyPortalApiController.PrepareDataGridObject(IEnumerable`1 list, DataManagerRequest dm) in C:\Users\rowan\RiderProjects\MyPortal\MyPortal\Controllers\Api\MyPortalApiController.cs:line 87
   at MyPortal.Controllers.Api.StudentsController.<GetAllStudentsDataGrid>d__3.MoveNext() in C:\Users\rowan\RiderProjects\MyPortal\MyPortal\Controllers\Api\StudentsController.cs:line 57
