无效的模板资源属性'Fn :: Base64'

Question

在处理ec2.json文件时出现上述错误

这是有效的JSON文件，请让我知道JSON文件的任何问题

   "Resources":{  
  "EC2Instance":{  
     "Type":"AWS::EC2::Instance",
     "Properties":{  
        "InstanceType":{  
           "Ref":"InstanceType"
        },
        "SecurityGroups":[  
           {  
              "Ref":"InstanceSecurityGroup"
           }
        ],
        "KeyName":{  
           "Ref":"KeyName"
        },

  "UserData":{  
     "Fn::Base64":{  
        "Fn::Join":[  
           "",
           [  
              "#!/bin/bash \n",
              "sudo apt-get update \n",
              "sudo apt-get install wget python -y \n",
              "echo UD_OF_EC2_1 >> /var/log/user-data.log \n",
              "echo UD_OF_EC2_2 >> /var/log/user-data.log \n",
              "echo UD_OF_EC2_3 >> /var/log/user-data.log \n"
           ]
        ]
     }
  },

我要附加的场景的最小可复制示例

请验证此模板是什么问题？ 我尝试从git hub编辑示例模板，以添加面对该问题的用户数据
