amazon-web-services - 属性 SubnetIds 的值必须是字符串列表类型错误

Question

我已经将subnetIds作为列表传递，但仍然收到错误:

  VpcEndpointSubnetIds:
    Type: "List<AWS::EC2::Subnet::Id>"
    Description: Select the subnet to associate with the VPC endpoint
    Default: 'subnet-039c1ac2c0925fe94,subnet-0e9267fe210b042da'

  VPCEndpointGateway:
      Type: AWS::EC2::VPCEndpoint
      Properties:
        VpcId: !Ref VpcId
        ServiceName: !Ref dynamoDbEndPointServiceName
        VpcEndpointType: Gateway
        PrivateDnsEnabled: true
        SubnetIds:
          -
            !Ref VpcEndpointSubnetIds
        SecurityGroupIds:
          -
            !Ref cacheSecurityGroup

不确定是什么导致了错误？我错过了什么吗？

更新:修复间距问题后，现在出现错误:

Value of property {/SubnetIds/0} does not match type {String}

Answer 1

这看起来像是模板格式问题。

此外，SubnetIds 属性仅受接口(interface) 和网关负载均衡器 VPC 终端节点类型支持。对于 Gateway 类型，您无法使用此属性，因此您需要将其删除:

  VPCEndpointGateway:
      Type: AWS::EC2::VPCEndpoint
      Properties:
        VpcId: !Ref VpcId
        ServiceName: !Ref dynamoDbEndPointServiceName
        VpcEndpointType: Gateway
        PrivateDnsEnabled: true
        SecurityGroupIds:
          - !Ref cacheSecurityGroup
