В настоящее время я делаю чат-бот на amazon lex и развернул его в slack. Но каким-то образом всякий раз, когда вы пытаетесь это сделать, и он достигает вопроса с ответной карточкой, он публикует повторный вопрос с подсказкой. Как сделать, чтобы он подсказывал только один раз или это просто проблема со Slack?
Вот мой код, используемый в aws lambda, однако я сделал настройки для карточки ответа на lex и ничего не сделал на aws lambda:
