无法使用 serverless.yml 创建 Lambda 和 Bucket

Question

我正在尝试使用无服务器框架创建一个基本的 lambda 和一个 S3 存储桶。我从这篇文章中剪下了一个小代码sn-p：Enable Lambda function to an S3 bucket using cloudformation

# serverless.yml

service: MyTest
provider:
  name: aws
  runtime: python3.7
resources:
  Resources:
    Bucket:
      Type: AWS::S3::Bucket
      Properties:
        BucketName: MyBucket12345
    MyFunc:
      Type: AWS::Lambda::Function
      Properties:
        Handler: handler.MyFunc


# handler.py

def MyFunc(event, context):
    print(event)

输出：

Serverless: Packaging service...

Serverless: Checking Stack create progress...

  TypeError: Cannot set property 'S3Key' of undefined

基于 cmets。

问题中提供的link 展示的是CloudFormation (CFN) template，而不是serverless framework template。两者虽然有相似之处，但不同。

问题中的代码是 CFN 和无服务器模板的混合体，这使得它在两个系统中都不起作用。

因此，要解决此问题，您必须检查并找到 examples 的无服务器框架模板，而不是 CFN。然后将当前模板修改为有效的无服务器模板。
