Я изучаю flask и пытался создать бэкэнд flask и создать остальные apis и использовать mongoengine для базы данных. python app.py работал успешно, но когда я передаю адрес электронной почты и пароль в почтальоне, я получаю The session is unavailable because no secret key was set. Set the secret_key on the application to something unique and secret при регистрации пользователя. может кто-нибудь помочь мне указать, где я ошибся?
