【问题描述】：
我正在尝试在 CloudFormation 中创建一个堆栈。当我完成该过程并填充字段时，系统会要求我输入 AMI。
我键入实例 ID，但在下一个屏幕上我收到以下错误消息：
There was an error creating this change set Parameter 'ami' must be one of AllowedValues
我不确定这里需要什么类型的参数。除了 ID 我还应该输入什么？
查看 AMI 详细信息，我看到 AMI 设置为私有。它不与任何帐户或组织共享。这就是它不起作用的原因吗？
我尝试用谷歌搜索该错误消息，但没有找到任何相关信息。
谢谢

-
请分享 CloudFormation 模板，或至少部分内容
-
我刚弄好了，谢谢你的帮助@Paolo

您的问题不清楚。您希望用户输入 AMI ID 还是希望用户从一组 ID 中进行选择？
-
您可以在模板中找到“AllowedValues”并使用列表中的值。也许你没有提供真实的。
