SignalR Irequest User is null

Question

I followed this answer but Im getting Null in Irequest request.User

SignalR - Sending a message to a specific user using (IUserIdProvider) *NEW 2.0.0*

I created a class in app_start folder like this

public class CustomUserIdProvider : IUserIdProvider
    {
        public string GetUserId(IRequest request)
        {
            // your logic to fetch a user identifier goes here.

            // for example:

            var userId = request.User.Identity.Name;
            return userId.ToString();
        }
    }

After this I initialize new costom provider in Startup.cs like this :

 public void Configuration(IAppBuilder app)
        {
            var idProvider = new CustomUserIdProvider();

            GlobalHost.DependencyResolver.Register(typeof(IUserIdProvider), () => idProvider);

            // Any connection or hub wire up and configuration should go here
            app.MapSignalR();
         }

But Im getting exception on line

var userId = request.User.Identity.Name;

System.NullReferenceException: 'Object reference not set to an instance of an object.'

make sure your user is authenticated, otherwise User property will be always null. — Roman.Pavelko, Dec 30 '19 at 22:58
No, login works fine.. I use User.Identity.Name on many other locations.. but it seems this is not same type — drma usama, Dec 31 '19 at 13:10
