  Hi there,

  Got this exception sometimes. I can't reproduce it unfortunately.

  2024-06-18 05:13:34.809 +00:00 [ERR] Unhandled exception in circuit '0Ii8lf77GLluHYmZrOx5tkCI26mNfhJH2DUyX1YmOpQ'. System.ObjectDisposedException: Instances cannot be resolved and nested lifetimes cannot be created from this LifetimeScope as it (or one of its parent scopes) has already been disposed. at Autofac.Core.Lifetime.LifetimeScope.ResolveComponent(ResolveRequest request) at Autofac.ResolutionExtensions.TryResolveService(IComponentContext context, Service service, IEnumerable1 parameters, Object& instance) at Autofac.ResolutionExtensions.ResolveService(IComponentContext context, Service service, IEnumerable1 parameters) at Microsoft.Extensions.DependencyInjection.ServiceProviderServiceExtensions.GetRequiredService[T](IServiceProvider provider) at Volo.Abp.ObjectMapping.DefaultObjectMapper.Map[TSource,TDestination](TSource source) at Volo.Abp.LanguageManagement.DatabaseLanguageProvider.bDKc3J4YN() at Volo.Abp.Caching.DistributedCache2.GetOrAddAsync(TCacheKey key, Func1 factory, Func1 optionsFactory, Nullable1 hideErrors, Boolean considerUow, CancellationToken token) at Volo.Abp.LanguageManagement.DatabaseLanguageProvider.GetLanguagesAsync() at Volo.Abp.AspNetCore.Components.Server.LeptonTheme.LeptonThemeToolbarContributor.ConfigureToolbarAsync(IToolbarConfigurationContext context) at Volo.Abp.AspNetCore.Components.Web.Theming.Toolbars.ToolbarManager.GetAsync(String name) at Volo.Abp.AspNetCore.Components.Web.LeptonTheme.Components.ApplicationLayout.MainHeader.MainHeaderToolbar.OnInitializedAsync() at Microsoft.AspNetCore.Components.ComponentBase.RunInitAndSetParametersAsync() at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle, ComponentState owningComponentState)

  How to fix that?

  Hi,

  According to log.txt file some other exceptions ocurred as well. I can't really explain why they occurred suddenly. A views exceptions:

  1. 2024-06-18 09:21:03.649 +00:00 [ERR] Unhandled exception in circuit 'SIhZtD4OOOkA9DL-XkSAqW_d-nKC2hSQ78CMzf6XNwE'.

  Do you have any clue why they occurred?

  Kind regards, Tako Verkroost

  hi

  System.ObjectDisposedException: Instances cannot be resolved and nested lifetimes cannot be created from this LifetimeScope as it (or one of its parent scopes) has already been disposed.

  Can you share a project to reproduce this? liming.ma@volosoft.com

  1.

  System.TimeoutException: Did not receive any data in the allotted time.

  This is not an abp exception. I have no idea.

  2. 3.

  2024-06-18 11:45:46.597 +00:00 [ERR] An exception occurred while iterating over the results of a query for context type 'Volo.Abp.LanguageManagement.EntityFrameworkCore.LanguageManagementDbContext'. System.Threading.Tasks.TaskCanceledException: A task was canceled. 2024-06-10 09:44:29.585 +00:00 [ERR] Connection id "0HN4967LSB6F1", Request id "0HN4967LSB6F1:00000002": An unhandled exception was thrown by the application.

  System.Threading.Tasks.TaskCanceledException: A task was canceled.

  You can ignore the TaskCanceledException

  4.

  2024-06-18 14:43:17.456 +00:00 [ERR] Unhandled exception in circuit '4NnRogiSjg5nPc_ppDUbJwo5Yyvfa4GPBshS89qJcJA'. System.InvalidOperationException: Collection was modified; enumeration operation may not execute.

  You can try to override the PageToolbarManager

  [ExposeServices(typeof(PageToolbarManager), typeof(IPageToolbarManager))]
  [Dependency(ReplaceServices = true)]
  public class MyPageToolbarManager : PageToolbarManager
  {
  
      public MyPageToolbarManager(IServiceScopeFactory serviceScopeFactory)
          : base(serviceScopeFactory)
      {
  
      }
  
      public async override Task<PageToolbarItem[]> GetItemsAsync(PageToolbar toolbar)
      {
          if (toolbar == null)
          {
              return Array.Empty<PageToolbarItem>();
          }
          
          var contributors = toolbar.Contributors.ToList();
          if (!contributors.Any())
          {
              return Array.Empty<PageToolbarItem>();
          }
  
          using (var scope = ServiceScopeFactory.CreateScope())
          {
              var context = new PageToolbarContributionContext(scope.ServiceProvider);
  
              foreach (var contributor in contributors)
              {
                  await contributor.ContributeAsync(context);
              }
  
              return context.Items.OrderBy(i => i.Order).ToArray();
          }
      }
  }
