Amazon web services 在我的IaC堆栈中获取自动存储桶策略的处理程序错误

我检查了lambda控制台，查看是否在其中写入了我的函数，并得到如下错误消息： “Lambda找不到文件Lambda_handler.py。请确保处理程序支持以下格式：file name.method。”

---

我的处理程序名为lambda_handler.py，那么为什么现在还不能工作呢？

创建的文件名为

index.py

因此，

Handler

属性将是

index.lambda\u Handler

。这是因为处理程序定义了与Lambda服务调用的函数组合的文件名

如上所述，该文件是

index.py

，但Lambda知道您的运行时，它只需要文件名的

索引部分，那么代码中定义的函数是
Lambda\u handler

更新处理程序值，这应该会起作用。
没问题，祝您愉快：）
