Amazon web services AWS Cloudformation创建堆栈模板错误

因此，我试图在CF中为API提供一些资源。我有下面的yml文件，但我一直得到一个模板错误，无法看到问题

当我运行它来创建堆栈时，它会给我一个错误

aws cloudformation创建堆栈--堆栈名称应用程序集群--模板正文file://infra/app-cluster.yml 错误是：

调用CreateStack操作时发生错误（ValidationError）：无效的模板属性或属性[？？？AWSTemplateFormatVersion]

当我删除前两行并将第一行设置为“Resources”时，我收到此错误

调用CreateStack操作时发生错误（ValidationError）：模板格式错误：必须至少定义一个Resources成员。

我觉得我必须错过一些简单的东西，但我就是看不到。谢谢

我已尝试使用UI创建您的模板，它正在工作。。AWS CLI命令似乎有问题。我猜YAML不知怎么被损坏了。也使用cli进行了检查，它工作了，您的文件100%损坏了。我尝试使用UI创建您的模板，它工作了。。AWS CLI命令似乎有问题。我猜YAML不知怎么被破坏了。也使用cli进行了检查，并且正常工作，您的文件100%被破坏了。谢谢。我疯狂地想弄清楚剧本本身到底出了什么问题！谢谢我疯狂地想弄清楚剧本本身到底出了什么问题！
