При первом входе в систему пользовательский контекст SignInManager имеет нулевое значение

Question

У меня возникла очень странная проблема, ответ на которую мне не очень очевиден. Я пытаюсь реализовать AS PNET CORE Identities (3.1), используя SignInManager и UserManager. Когда signinmanager пытается вызвать метод SignInWithClaimsAsyn c, он умирает с сообщением об ошибке, указывающим, что HTTPContext не должен быть нулевым. Я добавил HTTPContextAccessor, используя метод расширения, чтобы попытаться выяснить, не решило ли это проблему, но нет никаких изменений в поведении.

Ниже приведены соответствующие фрагменты кода:

Испытанные элементы: - Внедрение контекста прямо в signinmanager. Это приводит к удалению объекта.

Я могу предоставить хранилища пользователя / роли при необходимости.
