Cognito 用户池在配置为发送电子邮件时尝试发送 SMS

Question

我正在使用无服务器框架，以便使用以下 CloudFormation 配置创建 Cognito 用户池：

Resources:
  CognitoUserPool:
    Type: AWS::Cognito::UserPool
    Properties:
      # Generate a name based on the stage
      UserPoolName: ${opt:stage}-user-pool
      # Set email as an alias
      UsernameAttributes:
        - email
      AutoVerifiedAttributes:
        - email
      MfaConfiguration: OFF
      EmailVerificationMessage: 'message here'
      EmailVerificationSubject: 'subject here'
      Policies:
        PasswordPolicy:
          MinimumLength: 6
          RequireLowercase: true
          RequireNumbers: false
          RequireSymbols: true
          RequireUppercase: true
      Schema:
        - AttributeDataType: String
          DeveloperOnlyAttribute: false
          Mutable: true
          Name: address
          Required: true
        - AttributeDataType: String
          DeveloperOnlyAttribute: false
          Mutable: true
          Name: email
          Required: true
        - AttributeDataType: String
          DeveloperOnlyAttribute: false
          Mutable: true
          Name: family_name
          Required: true
        - AttributeDataType: String
          DeveloperOnlyAttribute: false
          Mutable: true
          Name: gender
          Required: true
        - AttributeDataType: String
          DeveloperOnlyAttribute: false
          Mutable: true
          Name: name
          Required: true
        - AttributeDataType: String
          DeveloperOnlyAttribute: false
          Mutable: true
          Name: phone_number
          Required: true
        - AttributeDataType: String
          DeveloperOnlyAttribute: false
          Mutable: true
          Name: website
          Required: true
        - AttributeDataType: String
          DeveloperOnlyAttribute: false
          Mutable: true
          Name: role
          Required: false
      EmailConfiguration:
        EmailSendingAccount: COGNITO_DEFAULT
        # The email is taken from command line arguments, the region and account id through pseudo parameters
        SourceArn: "arn:aws:ses:#{AWS::Region}:#{AWS::AccountId}:identity/${env:SES_EMAIL}"

如您所见，AutoVerifiedAttributes 设置为电子邮件；因此，Cognito 应该通过 SES 中配置的电子邮件发送验证码。但是我的 CI/CD 管道中出现以下错误：User pool does not have SMS configuration to send messages。关于为什么会发生这种情况的任何提示？

发现问题，其实和用户池无关。我有一个创建默认用户的资源，它没有设置 DesiredDeliveryMedium 属性;说 属性 默认为 SMS，设置为 EMAIL 就解决了。
