.AuthService.Logout() is with status code does not idicate success 500

Question

Hi, I Tried to implement an Authentication in my app all things works except LogOut.

I follow up this tutorial : https://codewithmukesh.com/blog/authentication-in-blazor-webassembly/#Authentication_State_Provider

When I click on Logout I received the message :

System.Net.Http.HttpRequestException: Response status code does not indicate success: 500 (Internal Server Error).
   at System.Net.Http.HttpResponseMessage.EnsureSuccessStatusCode()
   at FollowUpDash.Client.Services.AuthService.Logout() in C:\App\sbd\FollowUpDash\FollowUpDash\Client\Services\IAuthService.cs:line 36
   at FollowUpDash.Client.Services.CustomStateProvider.Logout() in C:\App\sbd\FollowUpDash\FollowUpDash\Client\Services\CustomStateProvider.cs:line 41
   at FollowUpDash.Client.Shared.MainLayout.LogoutClick() in C:\App\sbd\FollowUpDash\FollowUpDash\Client\Shared\MainLayout.razor:line 43

IAuthService.cs line 36

   public async Task Logout()
        {
            var result = await _httpClient.PostAsync("api/auth/logout", null);
            result.EnsureSuccessStatusCode();
        }

CustomStateProvder.cs line 41

  public async Task Logout()
        {
            await api.Logout();
            _currentUser = null;
            NotifyAuthenticationStateChanged(GetAuthenticationStateAsync());
        }

MainLayout.razor line 43

  async Task LogoutClick()
    {
        await authStateProvider.Logout();
        navigationManager.NavigateTo("/login");
    }

I don't know to fix this problem. Have you an idea?

Hi, I fix my problem.

The problem was in Program.cs

I've put app.UseRouting();

before

app.UseAuthentication();

app.UseAuthorization();

After this change Logout works.

Thanks to your support.
