Question

我创建了一个Cognito用户池，用户可以在其中注册但不能再次登录。我尝试了许多不同的配置，例如禁用MFA，关闭对设备的记忆，因为我认为这可能导致此问题，但无济于事。

最奇怪的是，在本地（localhost:5000）正常工作。我可以创建帐户并登录，没有任何麻烦，但是当我尝试在我的站点https://example.com（托管在S3上）上进行登录时，会出现上述错误。如果我注册，实际上用户似乎也可以在Cognito中创建-这样就可以了，但是登录只能在本地进行，而不能在任何地方进行。

我对每个设置，环境变量，创建的用户池等进行了两次，三次检查。

错误

这是我尝试登录时抛出的模棱两可的错误：

{
  __type: "NotAuthorizedException", 
  message: "Incorrect username or password."
}

预注册触发的lambda

我要先确认用户，然后再通过lambda进行注册：

import {INTERNAL_SERVER_ERROR} from 'http-status-codes';

export async function validateHumanViaSns(
    event: CognitoUserPoolTriggerEvent,
    context: Context,
    callback: Callback
): Promise<CognitoUserPoolTriggerHandler> {
    try {
        event.response.autoConfirmUser = true;

        callback(null, event);

        return;
    } catch (error) {
        console.error(error);
        callback(null, new Response(INTERNAL_SERVER_ERROR, {message: 'Something went wrong'}));

        return;
    }
}

对于为什么会抛出此特定错误（我认为这具有误导性）甚至更好，是否有人有任何想法？如何解决此问题？

Answer 1

此问题已在AWS Amplify Github问题积压more context here中解决。

无论何时导入amplify，由于amplify-js库中的Typescript编译问题，都需要直接直接导入crypto-js依赖项：

import 'crypto-js/lib-typedarrays'; // add this line
import Amplify, {Auth} from 'aws-amplify';

看来这将是未来拉取请求中的永久性修复程序，因此，根据您登陆的时间，尝试将aws-amplify软件包更新为> 1.1.19首先，先查看它是否已在主软件包中修复。
