aws-cloudformation - aws cloudformation - 资源属性错误

Question

我已经这样定义了我的参数:

{
    "PrivateSubnets":{
       "Description":"db subnetlist",
       "Type": "List<AWS::EC2::Subnet::Id>"
    },

    "VPCLIST": {
       "Description": "VPC list",
       "Type": "List<AWS::EC2::VPC::Id>"
    }
}

并在“资源”部分引用上述参数，如下所示:

    "InstanceSecurityGroup" : {
      "Type" : "AWS::EC2::SecurityGroup",
      "Properties" : {
        "VpcId" : {"Ref": "VPCLIST"} ,
        "GroupDescription" : "Enable 3306/80/SSH access via port 22"
}

在执行此操作时，我收到以下错误。

AWS::EC2::SecurityGroup InstanceSecurityGroup“属性 VpcId 的值必须为字符串类型”

注意:我只有默认 VPC 可用，该 VPC 不被视为字符串？此问题的任何解决方案...

正确的方法是进行此更改:

{
  "PrivateSubnets": {
    "Description":"db subnetlist",
    "Type": "AWS::EC2::Subnet::Id"
  },
  "VPCLIST": {
    "Description": "VPC list",
    "Type": "AWS::EC2::VPC::Id"
  }
}
