如何在不丢失登录用户的情况下更新我的 Cognito 用户池？

问题描述

我正在尝试从以下位置更新我的 Cognito 用户池：

Resources:
  CognitoUserPool:
    Type: AWS::Cognito::UserPool
    # Makes sure to delete the resource when the stack is deleted
    DeletionPolicy: Delete
    Properties:
      # Generate a name based on the stage
      UserPoolName: ${self:custom.cognito.user-pool}
      # Set email as an alias
      UsernameAttributes:
        - email
      AutoVerifiedAttributes:
        - email

到：

Resources:
  CognitoUserPool:
    Type: AWS::Cognito::UserPool
    # Makes sure to delete the resource when the stack is deleted
    DeletionPolicy: Delete
    Properties:
      # Generate a name based on the stage
      UserPoolName: ${self:custom.cognito.user-pool}
      # Set username as an alias
      AliasAttributes:
        - preferred_username
      AutoVerifiedAttributes:
        - email

允许我的用户拥有类似推特的用户名

尝试部署时，我收到以下错误消息：

  An error occurred: CognitoUserPool - Updates are not allowed for property - AliasAttributes. (Service: AWSCognitoIdentityProvider; Status Code: 400; Error Code: InvalidParameterException; Request ID: null; Proxy: null).

我想我可能需要删除我的池并从头开始重新创建它，但我不知道如何留住我的用户。

我该怎么做？
