Question

我试图创建一个requestValidator并通过
在我的请求中使用它 “ RequestValidatorId”：{ “参考”：“ PostRequestValidator” } 。
它应根据文档返回requestValidator的ID。
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-apigateway-requestvalidator.html

但是发生以下错误。

逻辑ID：postBannerMethod

Encountered unsupported property RequestValidatorId

您的RequestValidatorId是一个深入的层次。应该在AWS::ApiGateway::Method中，而不应该在Integration中：

建议在创作模板以及自动完成和文档链接时尝试在CloudFormation Linter中的VSCode内联查看其中一些错误：

[cfn-lint] E3002: Invalid Property Resources/postBannerMethod/Properties/Integration/RequestValidatorId

AWS Cloudformation-遇到不受支持的属性RequestValidatorId
