Cloudformation：ELB 侦听器规则创建失败 "Invalid request provided"

Question

我正在尝试建立一个由应用程序负载均衡器、目标组和 ECS 服务组成的小型 Cloudformation 堆栈。但是，堆栈无法创建 WidgetsServiceLbListenerRule 资源并出现以下错误：

"Invalid request provided: AWS::ElasticLoadBalancingV2::ListenerRule Validation exception" (RequestToken: 98057bbb-ad4f-5f09-3e89-cc6b645c6e7f, HandlerErrorCode: InvalidRequest)

为什么监听器规则创建失败？

这里是相关的堆栈代码：

Resources:

  # The load balancer
  Lb:
    Type: AWS::ElasticLoadBalancingV2::LoadBalancer
    Properties:
      Name: !Join ['', [!Ref Env, '-rest-api-lb-rev', !Ref Rev]]
      Scheme: internet-facing
      SecurityGroups:
        - !Ref LbSg
      Subnets:
        - Fn::ImportValue: !Sub "${VpcStackName}-PubSubnet1Id"
        - Fn::ImportValue: !Sub "${VpcStackName}-PubSubnet2Id"
        - Fn::ImportValue: !Sub "${VpcStackName}-PubSubnet3Id"
      Type: application
  LbListener:
    Type: AWS::ElasticLoadBalancingV2::Listener
    Properties:
      DefaultActions:
        - Type: fixed-response
          FixedResponseConfig:
            ContentType: text/plain
            MessageBody: The specified route doesn't exist
            StatusCode: 404
      LoadBalancerArn: !Ref Lb
      Port: 80
      Protocol: HTTP

  # Widgets service
  WidgetsServiceLbTargetGroup:
    Type: AWS::ElasticLoadBalancingV2::TargetGroup
    Properties:
      HealthCheckPath: /actuator/health
      Name: !Join ['', [!Ref Env, '-widgets-rev', !Ref Rev]]
      Port: 80
      Protocol: HTTP
      VpcId:
        Fn::ImportValue: !Sub "${VpcStackName}-VpcId"

  # THIS ONE FAILS TO CREATE
  WidgetsServiceLbListenerRule:
    Type: AWS::ElasticLoadBalancingV2::ListenerRule
    Properties:
      Actions:
        - Type: forward
          TargetGroupArn: !Ref WidgetsServiceLbTargetGroup
      Conditions:
        - Field: path-pattern
          Values:
            - '/widgets*'
      ListenerArn: Ref !LbListener
      Priority: 1
 
<ECS service and other assets omitted for brevity>

更多信息

我们的 AWS 帐户中有几个现有堆栈，它们使用几乎完全相同的代码。这些和这个之间没有任何有意义的区别，它们工作正常。
我创建了一个没有 WidgetsServiceLbListenerRule 的堆栈，然后尝试将其作为更改集添加回去。这也产生了同样的错误。
我能够使用以下 AWS CLI 命令成功创建规则：aws --profile clexp elbv2 create-rule --listener-arn <arn> --priority 1 --conditions file://conditions.json --actions file://actions.json

conditions.json:

[{"Type": "forward","TargetGroupArn": "<arn>"}]

actions.json:

[{"Field": "path-pattern","Values": ["/widgets*"]}]

非常感谢任何帮助。

而不是：

ListenerArn: Ref !LbListener

应该是：

ListenerArn: !Ref LbListener
