Я использую Heroku для развертывания Python API.Я использую Python для реализации Amazon понимания.Для этого я могу настроить ключи ACCESS и секретные ключи доступа в папке .aws с помощью команды aws configure в моей локальной системе.Работает нормально.Но когда я развернул в Heroku, он столкнулся с исключением, указывающим, что не удалось найти учетные данные.
Запускается в локальной системе, но исключение во время процесса развертывания Heroku.
Разница в локальномСистема и Heroku: Я создал виртуальную среду, а затем развернул в ней свое приложение, используя Heroku, во время развертывания.
Некоторые журналы, которыми я могу поделиться:
