NullReferenceException is thrown when page size dropdownlist is focused on or selected

Hi guys,


The error below is thrown when the DataGrid's page size Dropdown list is focused on or selected.

I mean the "Items per page" dropdown list.

The DataGrids in question are bound to an OData v4 data source.


 [Microsoft.AspNetCore.Components.Server.Circuits.RemoteRenderer] Unhandled exception rendering component: "Object reference not set to an instance of an object."

Any idea what the issue might be and when can I get a resolution?


Thanks,
