AWS SAM与带授权的部署无服务器Api有关的问题

Question

我想我在。yaml文件中做错了什么。可能是AWS::Serverless::Api的问题．在我添加之前，一切都很好。我只是想配置api授权。我还想知道如何配置哪些请求将被授权。我在部署命令后出现了这个错误:

初始部署

等待创建变更集。错误:Failed to create changesset for stack: SampleImagesApi, ex: Waiter ChangeSetCreateComplete Failed: Waiter遇到终端失败状态Status: Failed。原因:未解决的资源依赖[ServerlessRestApi]在模板的输出块

使用cfn-lintCLI来验证你的模板可以帮助你调试它- https://github.com/aws-cloudformation/cfn-python-lint

我在本地尝试了一下，有几个错误正在发生:
