Я ищу для хранения информации, которая хранится в сеансе, этот сеанс сначала инициализируется в маршрутизаторе индексов, где, если сеанса нет, он создаст его. Оттуда он отображает мою домашнюю страницу, на которой размещена форма. После отправки он вызывает мой маршрут /штамп, по которому я пытаюсь получить доступ к сеансу. Вот где возникает моя проблема, я возвращаюсь с неопределенным при попытке доступа req.session.stamp . Я пытался найти проблему в течение нескольких часов, любая обратная связь была бы очень полезна
