Closed ericzbeard closed 5 months ago

ericzbeard commented 6 months ago 
  PrivateSubnet1Subnet:
    Type: AWS::EC2::Subnet
    Properties:
    AvailabilityZone: !Select [0, Fn::GetAZs: ""]
    CidrBlock: 10.0.128.0/18
    MapPublicIpOnLaunch: false
    VpcId: !Ref VPC

The empty string (which means the same as AWS::Region) is converted to null
