Use same example described here. The error happens when BeginLogout is invoked.

@code{
    private async Task BeginLogout(MouseEventArgs args)
    {
        await SignOutManager.SetSignOutState();
        Navigation.NavigateTo("authentication/logout");
    }

    private void BeginLogin(MouseEventArgs args)
    {
        Navigation.NavigateTo("authentication/login");
    }
}

Authentication registration

   builder.Services.AddOidcAuthentication(options =>
            {
                builder.Configuration.Bind("Google", options.ProviderOptions);               
            });

Hey Damir!

I tried to repro your observation. Please see my small sample here: https://github.com/ChristianWeyer/blazor-wasm-oidc-google-repro

I was not able to obey the same error you are seeing. (Please make sure the redirect URLs in your Google app are configured correctly). Could you take a look and let me know whether I missed a scenario in my code @ddobric ? Thanks!
