Aws cognito通过管理节点js创建用户

我正在使用javascript sdk amazon-cognito-identity-js，并且我试图在nodejs中的cognito中创建用户，但错误即将来临下面是我的代码：-

var AWS = require("aws-sdk")
var params = {
    UserPoolId: "id",
    Username: req.body.username,
    DesiredDeliveryMediums: ["EMAIL"],
    ForceAliasCreation: false,
    TemporaryPassword: req.body.password,
    UserAttributes: [
      { Name: "name", Value: req.body.name },
      { Name: "email", Value: req.body.user_email}
    ],
 };
let client = new AWS.CognitoIdentityServiceProvider();
client.adminCreateUser(params, function(err, data) {
    if (err) {
        console.log("EE",err);
      //  reject(err);
    } else {
        console.log("DDD",data);
        //resolve(data);
    }
})

但是我使用代码收到此错误：-

EE {UnknownError：在Request.extractError上找不到（/var/task/node_modules/aws-sdk/lib/protocol/json.js:48:27）}

[请帮助我解决这个问题。

先决条件如果要在aws-sdk中使用凭证（手动过程）1.创建IAM用户并为您的用户分配一个Cognito角色。2.为该用户生成访问密钥和秘密密钥。3.在aws-sdk中使用该访问密钥和秘密密钥。

喜欢这个，

let AWS = require("aws-sdk"); AWS.config.update({ accessKeyId: "YOURKEY", secretAccessKey: "YOURSECRET", region: "YOURREGION" });

创建
CognitoIdentityServiceProvider类的对象
const COGNITO_CLIENT = new AWS.CognitoIdentityServiceProvider({
  apiVersion: "2016-04-19",
  region: "us-east-1"
});


var poolData = {
    UserPoolId: "XXXXXXXXX",
    Username: "[email protected]",
    DesiredDeliveryMediums: ["EMAIL"],
    TemporaryPassword: "Abc@321",
    UserAttributes: [
      {
        Name: "email",
        Value: "[email protected]"
      },
      {
        Name: "email_verified",
        Value: "true"
      }
    ]
  };
  COGNITO_CLIENT.adminCreateUser(poolData, (error, data) => {
    console.log(error);
    console.log(data);
    callback(null, {
      statusCode: 200,
      body: JSON.stringify(data)
    });
  });

否则，您无需在
AWS.config部分中设置凭据，就可以直接将IAM角色分配给EC2实例。
