SfBaseUtils System.NullReferenceException

[Sven Boris Bornemann]

Hi,

I get tons of exception logs in my Application. See below:

{ "Depth": 0, "ClassName": "System.NullReferenceException", "Message": "Object reference not set to an instance of an object.", "Source": "Syncfusion.Blazor", "StackTraceString": " at Syncfusion.Blazor.Internal.SfBaseUtils.UpdateDictionary(String key, Object data, Dictionary`2 dictionary)\n at Syncfusion.Blazor.DropDowns.SfDropDownList`2.DynamicPropertyUpdate()\n at Syncfusion.Blazor.DropDowns.SfDropDownList`2.OnParametersSetAsync()\n at Microsoft.AspNetCore.Components.ComponentBase.CallStateHasChangedOnAsyncCompletion(Task task)\n at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle)", "RemoteStackTraceString": null, "RemoteStackIndex": 0, "HResult": -2147467261, "HelpURL": null }

And I cannot see any further informations.... So I can also don't say in which control it happen.

Is there a way to get more informations about it? Because I cannot see where it comes from and when it happen.

Or is there a way to prevent it, because I'm afraid that my customers get every time a connection lost... Then the message is: Unhandled exception in circuit '"xxxxxx"'.

Thanks for the help.

Best regards Sven
