I was trying to create a requestValidator and use it in my request by
"RequestValidatorId": {
"Ref": "PostRequestValidator"
}
.
It should return the id of the requestValidator according to the doc.
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-apigateway-requestvalidator.html
But below error occurs.
Logical ID: postBannerMethod
Encountered unsupported property RequestValidatorId

Your RequestValidatorId is one level to deep. It should be in AWS::ApiGateway::Method, not in Integration:
