AWS CodePipeline“需要 AppSpec 文件，但在修订版本中找不到”

我正在尝试使用 CodeCommit、ECR 和 ECS 设置部署管道。我的管道很好地通过了源代码和构建步骤。如果我上传我的文件，我可以通过 CodeDeploy 手动部署appspec.yaml文件到 s3 存储桶。由 CodeCommit 存储库更改触发的部署总是失败并出现以下错误：

需要 AppSpec 文件，但在修订版中找不到

当我查看失败部署的详细信息时，我可以拉出修订位置，其中显示：

我看到在代码部署疑难解答 https://docs.aws.amazon.com/codedeploy/latest/userguide/troubleshooting-general.html#troubleshooting-text-editors某些编辑器可能会导致问题的部分。我在 Linux 上使用 vscode，所以我认为这不应该是一个问题。另外，如果我上传相同的应用程序规范文件到 s3 并从手动部署中引用它，它工作正常。

我也尝试过上传相同的文件，但名为appspec.yml。还是失败了。

此部署使用的角色具有完整的 s3 访问权限，不确定是否可能是任何其他与权限相关的问题。

这是我的代码管道定义：

“需要 AppSpec 文件，但在修订版本中找不到”

上述错误与您的 codepipeline 配置错误有关。要执行 ECS codedeploy 部署，codepipeline 阶段中用于部署的提供程序必须是“ECS（蓝色/绿色）”而不是“Codedeploy”（codedeploy 用于 EC2 部署。）

尽管在后端它使用codedeploy，但提供程序的名称是“ECS（蓝/绿）”。
