lambda 中的 AWS Cognito 用户池 AdminCreateUser 不返回错误也不返回数据答案

【问题标题】：AWS Cognito User Pool AdminCreateUser in lambda returns no error nor datalambda 中的 AWS Cognito 用户池 AdminCreateUser 不返回错误也不返回数据
【发布时间】：2020-09-19 03:50:24
【问题描述】：

我创建了一个 AWS Lambda 函数来测试新 Cognito 用户池帐户的创建，但没有在用户池中创建帐户，并且控制台日志中没有显示错误。我检查了 AWS Cloud Watch，但 Cloud Watch 也没有报错。

START RequestId: ..... Version: $LATEST
END RequestId: .....
REPORT RequestId: .....  Duration: 80.12 ms  Billed Duration: 100 ms Memory Size: 128 MB Max Memory Used: 84 MB

我将 Lambda 函数更改为更简单的函数；描述用户池。仍然没有引发错误，并且控制台中没有打印任何用户池信息。我在 describeUserPool 回调函数中添加了一个 console.log 打印，但没有打印。

lambda 函数是使用 AWS 控制台 Lambda 内联编辑器创建的。 Lambda 函数附加了 AmazonESCognitoAccess 策略（此策略具有对 Cognito 用户池的列表/读取/写入访问级别）。

谁能解释我做错了什么？非常感谢您。

var aws = require('aws-sdk');
aws.config.update({
    accessKeyId: 'access_key_id', 
    secretAccessKey: 'secret_access_key',
    region: 'us-east-1',
    apiVersion: '2016-04-18'
});
var cognito = new aws.CognitoIdentityServiceProvider();
var params = {
    UserPoolId: 'us-region-user-pool-id'
};

exports.handler = async (event) => {
    cognito.describeUserPool(params, function(err, data) {
        console.log('hello from inside function');
        if (err) {
            console.log(err);
        } else {
            console.log(data);
        }
     });
};

如果我在 AdminCreateUser 中包含不正确的参数，它会报告错误

var aws = require('aws-sdk');
    aws.config.update({
        accessKeyId: 'access_key_id', 
        secretAccessKey: 'secret_access_key',
        region: 'us-east-1',
        apiVersion: '2016-04-18'
    });


var cognito = new aws.CognitoIdentityServiceProvider();
var params = {
    UserPoolId: 'us-region-user-pool-id'
    Username: 'someone',
    TemporaryPassword: '11223344',
    DesiredDeliveryMediums: 'EMAIL',
    MessageAction: 'SUPPRESS',
    UserAttributes: [
    {
      Name: 'Email',
      Value: 'someone@example.com'
    },
    {
        Name: 'Family_Name',
        Value: 'One'
    },
    {
        Name: 'Given_Name',
        Value: 'Some'
    },
    {
        Name: 'Phone_Number_verified',
        Value: 'True'
    },
        {
        Name: 'Email_verified',
        Value: 'True'
    }

  ],
};

exports.handler = async (event) => {

    cognito.adminCreateUser(params, function(err, data) {
        console.log('hello from inside function');
        if (err) {
            console.log(err);
        } else {
            console.log(data);
        }
     });
};

我在 Lambda 内联编辑器控制台中收到以下错误消息：

嗨，你能看看它是否被调用。检查 CloudWatch 指标
在 Lambda 控制台中触发了“测试”，Cloud Watch 确认它运行了 successfully. Timestamp Message There are older events to load. Load more. 2020-05-31T16:59:07.766-04:00 START RequestId: 1ea1741e-d9e7-4991-af9d-f72bf73b1133 Version: $LATEST 2020-05-31T16:59:08.202-04:00 END RequestId: 1ea1741e-d9e7-4991-af9d-f72bf73b1133 2020-05-31T16:59:08.202-04:00 REPORT RequestId: 1ea1741e-d9e7-4991-af9d-f72bf73b1133 Duration: 434.49 ms Billed Duration: 500 ms Memory Size: 128 MB Max Memory Used: 83 MB Init Duration: 337.21 ms。但是，Cognito 没有 CloudWatch 指标。
我将函数调用改回 AdminCreateUser。这并没有产生任何 CloudWatch 日志。看起来 lambda 根本没有触发 CognitoIdentifyServiceProvider 函数调用。

【解决方案1】：

找到这个帖子cognito admin not giving error。 @thopaw 的建议解决了我遇到的问题。

通过将其更改为 promise() 基础，它可以按预期工作。谢谢你们的时间。

如果有人遇到这个，下面是更新的代码。

exports.handler = async (event, context) => {
    console.log('starts');
    var data;
    try {
        const data = await cognito.adminCreateUser(params).promise();
    } catch (error) {
        console.log(error);
    }
};
