Details:

ABP Framework version: v3.0.5
UI type: MVC Razor
Tiered (MVC) or Identity Server Seperated (Angular): unsure sorry, but I think it is Tiered (MVC)
Exception message and stack trace:
- 2020-08-31 11:54:33.262 +10:00 [ERR] Error when dispatching 'OnConnectedAsync' on hub. Autofac.Core.DependencyResolutionException: An exception was thrown while activating Castle.Proxies.ChatHubProxy. ---> Autofac.Core.DependencyResolutionException: None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder' on type 'Castle.Proxies.ChatHubProxy' can be invoked with the available services and parameters: Cannot resolve parameter 'Volo.Abp.Identity.IIdentityUserRepository identityUserRepository' of constructor 'Void .ctor(Castle.DynamicProxy.IInterceptor[], Volo.Abp.Identity.IIdentityUserRepository, Microsoft.AspNetCore.Identity.ILookupNormalizer)'. at Autofac.Core.Activators.Reflection.ReflectionActivator.GetValidConstructorBindings(ConstructorInfo[] availableConstructors, IComponentContext context, IEnumerable1 parameters) at Autofac.Core.Activators.Reflection.ReflectionActivator.ActivateInstance(IComponentContext context, IEnumerable1 parameters) at Autofac.Core.Resolving.InstanceLookup.CreateInstance(IEnumerable1 parameters) --- End of inner exception stack trace --- at Autofac.Core.Resolving.InstanceLookup.CreateInstance(IEnumerable1 parameters) at Autofac.Core.Resolving.InstanceLookup.Execute() at Autofac.Core.Resolving.ResolveOperation.GetOrCreateInstance(ISharingLifetimeScope currentOperationScope, ResolveRequest request) at Autofac.Core.Resolving.ResolveOperation.Execute(ResolveRequest request) at Autofac.ResolutionExtensions.TryResolveService(IComponentContext context, Service service, IEnumerable1 parameters, Object& instance) at Autofac.ResolutionExtensions.ResolveOptionalService(IComponentContext context, Service service, IEnumerable1 parameters) at Autofac.ResolutionExtensions.ResolveOptional(IComponentContext context, Type serviceType, IEnumerable1 parameters) at Autofac.ResolutionExtensions.ResolveOptional(IComponentContext context, Type serviceType) at Autofac.Extensions.DependencyInjection.AutofacServiceProvider.GetService(Type serviceType) at Microsoft.Extensions.DependencyInjection.ServiceProviderServiceExtensions.GetService[T](IServiceProvider provider) at Microsoft.AspNetCore.SignalR.Internal.DefaultHubActivator1.Create() at Microsoft.AspNetCore.SignalR.Internal.DefaultHubDispatcher1.OnConnectedAsync(HubConnectionContext connection) at Microsoft.AspNetCore.SignalR.Internal.DefaultHubDispatcher1.OnConnectedAsync(HubConnectionContext connection) at Microsoft.AspNetCore.SignalR.HubConnectionHandler1.RunHubAsync(HubConnectionContext connection) 2020-08-31 11:54:33.359 +10:00 [INF] Executed endpoint '/signalr-hubs/chat' 2020-08-31 11:54:33.360 +10:00 [INF] Request finished in 296.7416ms 101 `
Steps to reproduce the issue:
- Note: both IIdentityUserRepository and ILookupNormalizer fail to be resolved. (Removing them both) AND (hard-coding User Id OR sending messages to ALL users) works

Your kind help to resolve Volo.Abp.Identity.IIdentityUserRepository and Microsoft.AspNetCore.Identity.ILookupNormalizer (via Autofac) is greatly appreciated, please.

Thanks

Nick
