Asp.Net Core DefaultAuthorizationService runs twice for JWT tokens

I tried to create a AuthenticationScheme

JWT for tokens.

For my controller, I have an attribute [Authorize(Policy=Owner)]

.

This works, but I noticed in my debug log that this is happening:

Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerMiddleware: Info: Successfully validated token. Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerMiddleware: Info: AuthenticationScheme: TrustyBearer successfully authenticated. Microsoft.AspNetCore.Authorization.DefaultAuthorizationService: Information: Authorization was successful for user: af078cae-123b-4fa6-aacb-525dc5a4d5cb. Microsoft.AspNetCore.Authorization.DefaultAuthorizationService: Information: Authorization was successful for user: af078cae-123b-4fa6-aacb-525dc5a4d5cb.

It looks like the JWT middleware validates the token and then validates it again by the schema name. Twice or two different things?

But then I get two more identical messages Authorization was successful for user...

.

This happens even if I disable the policy name attribute and just use [Authorize]

.

I checked and I don't think I did something twice.

This is normal?

TIA
