AuthorizationHandlerContext returns null User in custom Authorization Handler

Question

I am trying to implement a custom authorization requirement, but it seems like context.User.Identity does not contain any data so the ClaimsPrincipal User.

• I added service and policy like this

   services.AddAuthorization(config =>
               {
                   config.AddPolicy("Test", policyBuilder =>
                   {
                       policyBuilder.UserRequireCustomClaim(0);
                   });
               });
  
   services.AddScoped<IAuthorizationHandler, TestHandler>();
  

my requirement, builder and handler are also set. How should I fix this problem in ASP.NET Core 3.0?

I found my problem after a good rest and reviewing my code, i just extended my IdentityUser but didnt send it to base;

public ApplicationUser() : base() { }

so context couldnt be represented inside the handler. Problem solved...
