Ask questionsNo DefaultChallengeScheme found from preview8 to preview9

Hello,

I just update my application to preview9 and i have a exception working with preview8.

System.InvalidOperationException: No authenticationScheme was specified, and there was no DefaultChallengeScheme found. The default schemes can be set using either AddAuthentication(string defaultScheme) or AddAuthentication(Action<AuthenticationOptions> configureOptions).

I change nothing except update to preview9 and asp package update. And i hacve already configure a auth.

services.AddAuthentication(options => { options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme; options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme; });

Kind regards,

aspnet/AspNetCore
