嗨，这是我的用于使用负载均衡器自动扩展的模板，并且我还附带了具有扩展/缩减策略的cpu警报，但是每当我要创建堆栈时，我都会收到错误消息，即无效的模板资源属性'WebServerScaleUpPolicy' 。所以，请让我知道我缺少的地方。
请帮帮我。 {AWS CloudFormation模板AutoScalingMultiAZ：创建在nginx Web Serever上运行的多中心，负载均衡和自动缩放的示例网站。该应用程序配置为跨越该地区的所有可用区，并根据Web服务器的CPU使用率自动缩放。
通过对默认网页进行简单的运行状况检查，可以对实例进行负载均衡。

您似乎还没有关闭LaunchConfig的括号。我已经修复了以下语法，AWS抛出此错误是因为WebServerScaleUp不是AWS::AutoScaling::LaunchConfiguration类型的属性。
