An error on creating of grid

I catch errors of grid using the method ActionFailure(Syncfusion.Blazor.Grids.FailureEventArgs args).

When the grid loading the first time the next error is sometimes catched:

System.ArgumentNullException: Value cannot be null. (Parameter 'source') at System.Linq.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument) at System.Linq.Enumerable.OfType[TResult](IEnumerable source) at Syncfusion.Blazor.Grids.SfGrid`1.VirtualDataProcess(List`1 QueryStartIndexes, ActionArgs action, DataReadyArgs`1 eventArgs) at Syncfusion.Blazor.Grids.SfGrid`1.DataProcessChild(ActionArgs action, ActionEventArgs`1 actionArgs) at Syncfusion.Blazor.Grids.SfGrid`1.DataProcess(ActionArgs action, ActionEventArgs`1 actionArgs)

This error is not critical and grid works. Anyway I want to find the source and correct it. Could you give advice where to look for?

Hi Renjith,

No I check if my custom data adaptor returns DataResult with null Result. I hope it will solve the trouble. Otherwise I will write
