Using absolute URIs for the RedirectUri and LogoutUri causes an exception on production.

For the advise on setting the RedirectUri and LogoutUri, it should be a relative path, as absolute URIs are not guaranteed to work, such as in my own case: https://github.com/DuendeSoftware/Support/issues/750

https://learn.microsoft.com/en-us/aspnet/core/security/authentication/identity-api-authorization?view=aspnetcore-6.0#configuration-through-appsettings

The advise should be to set these URIs to relative paths: "/authentication/login-callback" and "/authentication/logout-callback" respectively

This is the error I was getting when using absolute URIs instead:
