ReduxDevToolsMiddleware: An exception occurred while dispatching a location changed event

[mohaaron]

I'm getting the following error in the Counter component after adding my state object to it. Any idea why? I've been receiving this error in another project as well and had to remove DevTools from the configuration to get rid of the error.

https://github.com/mohaaron/Syncfusion.Blazor.Demo/blob/trunk/BlazorSyncfusion.Demo/Pages/Counter.razor

fail: Microsoft.AspNetCore.Components.Server.Circuits.CircuitHost[219]
Location change to 'https://localhost:7081/counter' in circuit '_yK0X86L7bjCCtBD30RGdUhSceak5-gO6A2Yub-Ve5M' failed.
