Question

我正在尝试将django应用程序部署到AWS Lambda。我已经看过许多有关如何这样做的教程。但是，每当运行zappa deploy时，最后都会出现以下错误：

Deploying API Gateway.. Error: Warning! Status check on the deployed lambda failed. A GET request to '/' yielded a 502 response code.

运行zappa tail可为我提供以下信息：

我在做什么错？我已经定义了所有环境变量的settings.py。似乎这些变量没有被正确读取？太感谢所有这些。

不是真正的解决方法，而是一种解决方法。我使用的是AWS RDS MySQL，然后将所有内容都更改为AWS RDS PostgreSQL。没问题。这让我相信错误与连接到MySQL有关。
