amazon-web-services - AWS 中此 Cloudformation 模板中的内在函数 !Ref 的错误是什么？

Question

最近我开始探索 YAML 格式的 AWS CloudFormation。我收到错误消息:

Encountered unsupported property Type

YAML代码说明如下:-

AWSTemplateFormatVersion: 2010-09-09
Resources: 
  DevEC2Instance:
    Type: 'AWS::EC2::Instance'
    Properties:
      ImageId: ami-04aa88aebb9fefd83
      Type: t2.micro
      KeyName: Newkey
      SecurityGroups:
       - default
       - !Ref SSHSecurityGroup
SSHSecurityGroup:
  Type: AWS::EC2::SecurityGroup
  Properties:
    GroupDescription: Group_For_CloudFormation
    SecurityGroupIngress:
    - Ipprotocol: tcp
      FromPort: '22'
      ToPort: '22'
