Я пытаюсь подключить токен jwt к своему проекту, и во время работы у меня возникают некоторые проблемы. Я следовал инструкции, упомянутой здесь , но у меня есть ошибки. Я пытался исправить это с той же проблемой от этих парней , но у меня это не сработало. Я думаю, я что-то упускаю.
Может кто-нибудь, пожалуйста, помогите мне, спасибо.
Ошибка:
