Cloudformation模板錯誤 - 模板驗證錯誤：模板格式錯誤：每個Mappings成員類型必須是地圖

Question

我有一個cloudformation模板。

它應該創建一個EC2實例，更改Adminstrator密碼並重命名服務器。

我將幾個參數傳遞給堆棧模板。當我運行它時，它會給出「模板格式錯誤：每個映射成員類型必須是一個映射」。

我確保我在模板中提到的任何內容都位於「映射」部分。不知道爲什麼我得到這個錯誤。

任何建議是非常有幫助的。

我和yaml模板有同樣的問題。 它看起來像只有2級映射在模板的支持，所以你需要酌情添加另一個級別，例如，

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