所以，我目前遇到了这个问题，但没有多大意义，因为我已经添加了类型LoadBalancerListener......我之前已经测试过Load Balancer和Target Group，然后它们运行良好，但是当我添加时Listener，堆栈得到一个错误。这是代码：

AWSTemplateFormatVersion: 2010-09-09
Description: Template for load balancer

Resources: 
  DayOne:
    Type: AWS::ElasticLoadBalancingV2::LoadBalancer
    Properties:
      Scheme: internet-facing
      SecurityGroups:
        - sg-055ea833725644075
      Subnets:
        - subnet-0d7b9bf57973e6b78
        - subnet-0186890795288d48a
  LoadBalancerListener:
    Type: AWS::ElasticLoadBalancingV2::Listener
    Properties:
      DefaultActions:
        - Type: forward
        - TargetGroupArn: !Ref TargetGroup
      LoadBalancerArn: !Ref DayOne
      Port: 80
      Protocol: "HTTP"
  TargetGroup:
    DependsOn: "DayOne"
    Type: AWS::ElasticLoadBalancingV2::TargetGroup
    Properties: 
      TargetType: "instance"
      Name: "DayOneTarget"
      Port: 80
      Protocol: "HTTP"
      VpcId: "vpc-0f98d22c9291e3c0c"
      HealthyThresholdCount: 2
      HealthCheckTimeoutSeconds: 10
      HealthCheckIntervalSeconds: 30

这是问题所在：
