2 months ago No they are different components.
Volo.Abp.AspNetCore.Components.Server.LeptonXLiteTheme.Themes.LeptonXLite.Toolbar.UserMenuComponent
If someone can point me to the source code I can probably determine the exact line of code.
It happens after authentication and the redirect. I think it's a ICurrentUser check and it's null.

1 month ago For those experiencing the error the work around is to create a class that inherits from the MobileUserMenuComponent and to override the SetParametersAsync
using Microsoft.AspNetCore.Components; using Volo.Abp.DependencyInjection; using MobileUserMenuComponent = Volo.Abp.AspNetCore.Components.Server.LeptonXLiteTheme.Themes.LeptonXLite.Toolbar.MobileUserMenuComponent;
namespace YourDotNet8Namespace;
[ExposeServices(typeof(MobileUserMenuComponent))] [Dependency(ReplaceServices = true)] public partial class OverrideMobileUserMenuComponent : MobileUserMenuComponent { public string Name = "My Mobile User Menu Component";
public override async Task SetParametersAsync(ParameterView parameters)
{
//await base.SetParametersAsync(parameters); //<================ GARBAGE HACK
}}

1 month ago I can't reproduce the problem with latest version.
abp new BookStore -u blazor-server --tiered -t app --old
Is there an existing issue for this?
