我正在尝试使用 SAM cli 部署 aws lambda 函数。我在 sam 模板中定义了一些层。使用 sam local start-api
进行本地测试效果很好。但是使用 sam deploy --guided
命令进行部署会引发以下错误Error: Failed to create changeset for the stack: sam-app, ex: Waiter ChangeSetCreateComplete failed: Waiter encountered a terminal failure state: For expression "Status" we matched expected path: "FAILED" Status: FAILED. Reason: Template format error: Unresolved resource dependencies [arn:aws:lambda:us-west-1:338231645678:layer:ffmpeg:1] in the Resources block of the template
SAM模板如下

任何想法我做错了什么?
最佳答案
您正在尝试引用一个不存在的逻辑 ID。
只需将图层的'ffmpeg'的ARN
:
Layers:
- !Ref VideoProcessorDepLayer
- arn:aws:lambda:us-west-1:338231645678:layer:ffmpeg:1
