Amazon cloudformation 由于未找到处理程序错误，无法部署aws sam堆栈

使用

sam

在嵌套目录中部署带有处理程序的lambda时遇到问题

我执行以下步骤：

包装：

sam包--template template.yaml--输出模板文件packated.yaml--s3 bucket

创建我在下一步中使用的packaged.yaml

部署：

aws cloudformation部署--模板文件/Users/localuser/Do/learn sam/dynamo stream lambda/package.yaml--堆栈名barkingstack

错误

Failed to create the changeset: Waiter ChangeSetCreateComplete failed: Waiter encountered a terminal failure state Status: FAILED. Reason: Transform AWS::Serverless-2016-10-31 failed with: Invalid Serverless Application Specification document. Number of errors found: 1. Resource with id [PublishNewBark] is invalid.

我相信您必须将除资源类型之外的所有内容都放在“属性”下

您的函数声明应该是：
