Cloudformation模板错误 - 模板验证错误：模板格式错误：每个Mappings成员类型必须是地图

问题描述：

我有一个cloudformation模板。Cloudformation模板错误 - 模板验证错误：模板格式错误：每个Mappings成员类型必须是地图

它应该创建一个EC2实例，更改Adminstrator密码并重命名服务器。

我将几个参数传递给堆栈模板。当我运行它时，它会给出“模板格式错误：每个映射成员类型必须是一个映射”。

我确保我在模板中提到的任何内容都位于“映射”部分。不知道为什么我得到这个错误。

任何建议是非常有帮助的。

这怎么不是一个有效的问题吗？这个论坛是疯了。请解释为什么我的问题被拒绝投票？ – jason

我和yaml模板有同样的问题。它看起来像只有2级映射在模板的支持，所以你需要酌情添加另一个级别，例如，

... 
"QRMEnvironmentType" : 
{ 
    "Description" : {"Value": "QRM Dev, test, or Prod Platform"}, 
    "Type"   : {"Value": "String"}, 
    ... 
} 
...
