Check the docs before asking a question: https://docs.abp.io/en/commercial/latest/ Check the samples, to see the basic tasks: https://docs.abp.io/en/commercial/latest/samples/index The exact solution to your question may have been answered before, please use the search on the homepage.

If you're creating a bug/problem report, please include followings:

  • ABP Framework version: v7.0.1
  • UI type: Blazor Wasm
  • DB provider: EF Core
  • Tiered (MVC) or Identity Server Separated (Angular): no
  • Exception message and stack trace: crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100] Unhandled exception rendering component: Value cannot be null. (Parameter 'str') System.ArgumentNullException: Value cannot be null. (Parameter 'str') at Volo.Abp.Check.NotNull[String](String value, String parameterName) at System.AbpStringExtensions.EnsureEndsWith(String str, Char c, StringComparison comparisonType) at Volo.Chat.Blazor.WebAssembly.Components.BlazorMessagesToolbarItem.SetChatHubConnectionAsync() at Volo.Chat.Blazor.Components.MessagesToolbarItem.OnInitializedAsync() at Microsoft.AspNetCore.Components.ComponentBase.RunInitAndSetParametersAsync() at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle, ComponentState owningComponentState)
  • Steps to reproduce the issue:" Add chat module through ABP Suite. Enable the chat feature from the admin menu. Logout and login again. You get the above error in the browser console. I get the above error after adding the Chat feature to my application. I believe the error occurs when this is invoked; Volo.Chat.Users.ContactController.GetTotalUnreadMessageCountAsync. I even get same error on activating chat on the default/blank blazor wasm project.
