使用CloudFormation的API网关的自定义域

Question

我正在尝试使用CloudFormation为API网关定义自定义域（实际上是子域）。根据所有文档，我已经能够找到以下内容，但是在部署它时，我得到Invalid domain name identifier specified了BasePathMapping

aws cloudformation deploy --template-file packaged-prompt.yaml --capabilities CAPABILITY_IAM --stack-name prompt-stack

提示

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31

Resources:

  ...

  Certificate:
    Type: 'AWS::CertificateManager::Certificate'
    Properties:
      DomainName: example.mydomain.com

  DomainName:
    Type: 'AWS::ApiGateway::DomainName'
    Properties:
      CertificateArn: !Ref Certificate
      DomainName: example.mydomain.com

  Mapping:
    Type: 'AWS::ApiGateway::BasePathMapping'
    Properties:
      DomainName: !Ref DomainName
      RestApiId: !Ref Api

  Api:
    Type: AWS::Serverless::Api
    Properties:
      StageName: prod
      DefinitionBody:
        swagger: 2.0
