PerformFiltering fails on an IQuerable datasource with Include

[Vahid Rassouli]

Hi

I'm using ej2 DataGrid on an MVC Core project.

Following the samples, I could setup a running datagrid with some data source of type IQuerable successfully.

Everything like filtering, searching and sorting works fine using DataOperations object.

But as soon as I include some navigation properties on my datasource, it fails and complains of Null reference exception.

Is this a bug or known issue and are there any workarounds on this?

Thanks
