AWS SAM部署错误-验证错误| CreateChangeSet操作错误

Question

我在尝试sam部署-引导我的lambda应用程序时收到以下错误。

错误:未能为堆栈创建变更集:{stack-name}，调用create changeset操作时出错(validation error):Stack:arn:AWS:cloud formation:AP-southeast-2:014009325916:Stack/{ Stack-name }/f 2212 bf0-bb41-11ea-8e F3-0aa 7 af 0536 b 6处于ROLLBACK_COMPLETE状态，无法更新。

这个问题的进一步上下文是我的所有 lambda 函数都没有定义授权。不确定这是否相关，但我是在说明的情况下。

坦率地说，我不知道如何着手处理这个问题。感谢任何帮助。

Answer 1

可能需要先运行sambuild，这样您的资源才能获得最新的更改

Answer 2

据我了解，当一个人进行初始部署并且初始部署失败时，会遇到错误。因此，某些内容会中断，部署服务无法成功执行。要解决此问题，只需删除 aws cloudformation 堆栈并重新部署即可。

可以使用以下命令删除：

AWS Cloudformation 删除堆栈 --堆栈名称
