如何在 cloudformation 堆栈中为 lambda 配置 asynconfig？

Question

I created a cloud formation stack as below, I'm setting MaximumRetryAttempts: 1, but once the function is created the retry events is always set to 2 ( attached screenshot). how can i change the value of this.

HelloWorldLambdaFunction:
    Type: AWS::Lambda::Function
    Properties:
      FunctionName: hello-world
      Runtime: python3.7
      Handler: index.lambda_handler
   version:
     Type: AWS::Lambda::Version
     Properties:
       FunctionName: !Ref HelloWorldLambdaFunction
   asynconfig:
     Type: AWS::Lambda::EventInvokeConfig
     Properties:
       FunctionName: !Ref HelloWorldLambdaFunction
       MaximumRetryAttempts: 1
       Qualifier: !GetAtt version.Version

The code looks fine. However, it seems to me that you are viewing $LATEST version in the console.

However, you set the asynconfig for version 1 . Thus, in the console you have to explicitly select the correct lambda function version:

Update

To use latest version:

  asynconfig:
    Type: AWS::Lambda::EventInvokeConfig
    Properties:
      FunctionName: !Ref HelloWorldLambdaFunction
      MaximumRetryAttempts: 1
      Qualifier: $LATEST
