Question

我正在使用此CloudFormation模板创建Cognito用户池：

                }
            }
        }
    }
}

"Schema"是当前有效的用户池的输出：

aws cognito-idp describe-user-pool --user-pool-id POOL_ID

即使堆栈有效，我在创建堆栈（当然使用其他名称）时也会遇到此错误：

检测到1个验证错误：“ schema.18.member.name”上的值“ phone_number_verified”未能满足约束：成员的长度必须小于或等于20（服务：AWSCognitoIdentityProviderService；状态代码：400；错误代码： InvalidParameterException；请求ID：ID）

phone_number_verified是布尔值。

Answer 1

问题是：名称：“ phone_number_verified”太长（超过20个字符）。将其更改为“ phonenumber_verified”之类的名称即可。

注意：命令aws cloudformation validate-template将无法捕获。

Answer 2

我得到的错误是这个，

1 validation error detected: Value 'custom:cognitoIdentityId' at 
'schema.3.member.name' failed to satisfy constraint: .
Member must have length less than or equal to 20 
(Service: AWSCognitoIdentityProviderService; Status Code: 400; 
Error Code: InvalidParameterException; 
Request ID: 2c7c69a9-68ca-4ccc-a951-ab3fa0be2689)

因此，“名称”属性过长。名称属性的值为“ custom：cognitoIdentityId”。

根据文档，最小值：1，最大值：20。

Answer 3

该提示出现在错误消息中，但我同意它极具误导性。它没有提到它指向哪个Member。对于此api，它是您上面的Schema属性。

您会注意到Schema下有21个属性。由于API一次最多接受20个，因此您可以删除任何一个属性，然后重试。我认为，一旦使用20种资源进行创建，就应该能够将其重新添加。
