Is there any chance to get more detailed error message?

I have very large grid which generates sometime the next error:

blazor.server.js:21 [2021-11-09T12:46:08.907Z] Error: 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)

   at Syncfusion.Blazor.Grids.SfGrid`1.DataProcess(ActionArgs action, ActionEventArgs`1 actionArgs)

   at Syncfusion.Blazor.Grids.SfGrid`1.OnAfterScriptRendered()

   at Syncfusion.Blazor.SfBaseComponent.OnAfterRenderAsync(Boolean firstRender)

   at Syncfusion.Blazor.SfDataBoundComponent.OnAfterRenderAsync(Boolean firstRender)

   at Syncfusion.Blazor.Grids.SfGrid`1.OnAfterRenderAsync(Boolean firstRender)

   at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle)


I understand that the error could be probably somewhere in column templates. But more detailed information would be very useful. Of course, I tried to comment out part of columns, and sometimes it helped to find the error. But if you would able to definitely mention the source of mistake, debug would be much faster.
