Я развернул flask twilio chatbot на AWS lambda, используя zappa. Однако, когда я пытаюсь запустить чат-бота, я получаю сообщение об ошибке: 

Error - 11200
...  Msg=Internal+Server+Error&sourceComponent=14100&ErrorCode=11200&EmailNotification=false&httpResponse=500&LogLevel=ERROR&url=https%3A%2F%2Ft6ps265p77.execute-api.us-east-1.amazonaws.com%2Fdev%2Fbot

на моем отладчике Twilio. Я впервые пытаюсь развернуть что-либо на AWS, и у меня очень ограниченный опыт работы с AWS. Это код для приложения

if __name__ == '__main__':
    app.run(debug=True)

Это мои zappa_settings. json: 

{
    "dev": {
        "app_function": "bot.app",
        "profile_name": null,
        "project_name": "xxx",
        "runtime": "python3.7",
        "s3_bucket": "zappa-xxx",
        "aws_region": "us-east-1"
    }

и мои настройки на twilio 

WHEN A MESSAGE COMES IN: https://t6ps265p77.execute-api.us-east-1.amazonaws.com/dev/bot

Приложение запускается, если я запускаю его локально с помощью ngrok
