无法使用CloudFormation创建ECS部署组（loadBalancerInfo错误）

【以下的问题经过翻译处理】 我无法使用CloudFormation模板创建ECS部署组，并收到下面的错误消息。

For ECS deployment group, loadBalancerInfo must not contain targetGroupInfo list (Service: AmazonCodeDeploy; Status Code: 400; Error Code: InvalidLoadBalancerInfoException; Request ID: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx; Proxy: null)

我的CFn模板片段如下。 我已注释掉“TargetGroupInfoList”以消除错误消息，但它没有起作用（得到完全相同的错误消息）。

# CodeDeploy Deployment groups
  DeploymentGroup:
    Type: AWS::CodeDeploy::DeploymentGroup
    Properties: 
      ApplicationName: !Ref DeployApplication
      DeploymentStyle:
        DeploymentType: BLUE_GREEN
        DeploymentOption: WITH_TRAFFIC_CONTROL
      BlueGreenDeploymentConfiguration:
        DeploymentReadyOption:
          ActionOnTimeout: CONTINUE_DEPLOYMENT
        TerminateBlueInstancesOnDeploymentSuccess:
          Action: TERMINATE
          TerminationWaitTimeInMinutes: 5
      DeploymentConfigName: CodeDeployDefault.OneAtATime
      DeploymentGroupName: myapp-dg
      ECSServices:
        - ClusterName: !Ref ECSCluster
          ServiceName: !GetAtt ECSService.Name
      LoadBalancerInfo:
        ElbInfoList: 
          - Name: !Ref ALB
#        TargetGroupInfoList:
#          - Name: !Ref TargetGroup01
#          - Name: !Ref TargetGroup02
      ServiceRoleArn: arn:aws:iam::xxxxxxxx:role/CodeDeployServiceRole

如何在模板中定义“LoadBalancerInfo”？
