Azure devops Azure DevOps AWS CloudFormation创建/更新堆栈任务-失败'；堆栈不存在'；

我有一个发布管道配置为使用AWS CloudFormation创建/更新堆栈任务。任务配置为使用更改集，如下所示：

然而，由于某种原因，管道不断出现故障。它失败是因为它测试堆栈的存在，发现它不存在，切换到“创建”模式，但随后测试更改集的存在，失败是因为更改集也不存在？？这毫无意义

您可以通过以下步骤对问题进行故障排除：

首先检查用于创建AWS凭据的AWS帐户是否具有

cloudformation:DescribeCacks

和

cloudformation:DescribeCackEvents权限。如果使用IAM角色创建AWS凭据服务连接。您需要确保已将上述权限分配给角色。看

确保您选择了正确的AWS地区。因为云的形成是区域性的

手动删除已存在的堆栈，或使用AWS CloudFormation删除堆栈
创建前删除堆栈的任务。有关信息，请参见下面的线程


这是YAML模板本身的多个小语法错误，例如Ref参数的使用方式。不幸的是，错误消息并没有真正帮助发现这是一个问题，此外，SAM CLI validate命令确认模板有效

尽管如此，现在有了一个固定且有效的无服务器YAML模板，管道仍在运行
