Amazon web services 无法创建AWS Cognito用户池用户

我正在尝试使用Cognito用户池控制台创建一个用户（我正在设置用户名和临时密码的值），但我一直收到这个错误

属性不符合架构：生日：编号不能超过10个字符（服务：AWSCognitoIdentityProviderService；状态代码：400；错误代码：InvalidParameterException；请求ID:98f3de9e-5ce3-11e7-98e8-9d0c69d31df9）

用户池是使用serverless创建的

Type: AWS::Cognito::UserPool
  DeletionPolicy: Retain
  Properties:
    UserPoolName: employees
    AdminCreateUserConfig:
      AllowAdminCreateUserOnly: true
    Policies:
      PasswordPolicy:
        MinimumLength: 8
        RequireLowercase: true
        RequireNumbers: true
    Schema:
      - Name: "picture"
        AttributeDataType: String
        Mutable: true
        Required: false
      - Name: "given_name"
        AttributeDataType: String
        Mutable: true
        Required: true
      - Name: "middle_name"
        AttributeDataType: String
        Mutable: true
        Required: false
      - Name: "family_name"
        AttributeDataType: String
        Mutable: true
        Required: true
      - Name: "address"
        AttributeDataType: String
        Mutable: true
        Required: false
      - Name: "birthdate"
        AttributeDataType: String
        Mutable: true
        Required: true
      - Name: "gender"
        AttributeDataType: String
        Mutable: true
        Required: true

一定很晚了，但请尝试下面的代码，我定义了MinLength和MaxLength：

Type: AWS::Cognito::UserPool
  DeletionPolicy: Retain
  Properties:
    UserPoolName: employees
    AdminCreateUserConfig:
      AllowAdminCreateUserOnly: true
    Policies:
      PasswordPolicy:
        MinimumLength: 8
        RequireLowercase: true
        RequireNumbers: true
    Schema:
      - Name: "picture"
        AttributeDataType: String
        Mutable: true
        Required: false
      - Name: "given_name"
        AttributeDataType: String
        Mutable: true
        Required: true
      - Name: "middle_name"
        AttributeDataType: String
        Mutable: true
        Required: false
      - Name: "family_name"
        AttributeDataType: String
        Mutable: true
        Required: true
      - Name: "address"
        AttributeDataType: String
        Mutable: true
        Required: false
      - Name: "birthdate"
        AttributeDataType: String
        Mutable: true
        Required: true
        DeveloperOnlyAttribute: false
        StringAttributeConstraints: 
          MinLength: "10"
          MaxLength: "10"
      - Name: "gender"
        AttributeDataType: String
        Mutable: true
        Required: true
