Cloudwatch 事件不会触发通过 CloudFormation 创建的 Lambda 函数

问题描述

请找到我尝试使用 cloudformation 创建 lambda 函数和事件规则的代码，cloudformation 已成功部署，一切看起来都不错，但在计划时间我的事件规则没有触发或调用 lambda 函数，我有检查权限也一切正常，但不起作用。

请您在这里帮忙。

  CRONScheduler:
    Description: 'Define the CRON Schedule for the event to trigger'

      Targets:
        -
          Arn:
            Fn::GetAtt:
              - "LambdaFunction"
              - "Arn"
          Id: "TargetFunctionV1"
          Input: '{"Account_id ": "369885648310"}'

  PermissionForEventsToInvokeLambda:
    Type: AWS::Lambda::Permission
    Properties:
      FunctionName: !Ref LambdaFunction
      Action: "lambda:InvokeFunction"
      Principal: "events.amazonaws.com"
      SourceArn:
        Fn::GetAtt:
          - "EventRule"
          - "Arn"

  LambdaFunction:
    Type: AWS::Lambda::Function
    Properties:
      Description: "My Lambda Function"
      FunctionName: "MyLambdaFunccc"
      Role: arn:aws:iam::369885648310:role/service-role/myfunction-role-cjkkxygt
      Runtime: python3.8
      #Code:
      #  ZipFile: |
      #      import boto3
      #      def lambda_handler(event,context):
      #        client = boto3.client('ec2')
      #        response = client.describe_instances(InstanceIds = ['i-03de56c4f3969694a'])
      #        for instance in response['Reservations']:
      #          for depth in instance['Instances']:
      #            print('the machine details are {},{},{}'.format(depth['ImageId'],depth['InstanceType'],depth['Monitoring']))

      #Handler: index.lambda_handler
      Code:
        S3Bucket: cftfiles
        S3Key: InstanceStateChange.zip
      Handler: InstanceStateChange.lambda_handler
