Cognito adminDeleteUser用户池不存在错误

Question

为什么如下代码所示的AWS Cognito adminDeleteUser函数会给出“用户池不存在”错误消息？

const aws = require('aws-sdk');
aws.config.accessKeyId = 'aaaaaaa';
aws.config.secretAccessKey = 'sssssss';
aws.config.region = 'us-west-2';
const CognitoIdentityServiceProvider = new 
aws.CognitoIdentityServiceProvider();
global.fetch = require('node-fetch');
const AmazonCognitoIdentity = require('amazon-cognito-identity-js');

// this section of code produces a correct userPool object
let poolData =
{
    UserPoolId: 'ppppppp',
    ClientId: 'ccccccc'
};
let userPool = new AmazonCognitoIdentity.CognitoUserPool(poolData);
console.log('userPool: ', userPool);

// this section of code reports error: "ResourceNotFoundException: 
User pool ppppppp does not exist."
let params =
{
    UserPoolId: 'ppppppp',
    Username: 'nnnnnnn'
};
CognitoIdentityServiceProvider.adminDeleteUser(params, (err,data) =>
{
    if (err) console.log(err);
    else console.log('user deleted');
});

问题已通过更改代码自

解决

aws.config.accessKeyId = 'aaaaaaa';
aws.config.secretAccessKey = 'sssssss';
aws.config.region = 'us-west-2';

到以下

aws.config.update(
{
    accessKeyId: 'aaaaaaa',
    secretAccessKey: 'sssssss',
    region: 'us-west-2'
});

还请注意，无论是否提供有效的UserPoolId值，以下代码都会创建一个userPool对象：

let poolData =
{
    UserPoolId: 'ppppppp,
    ClientId: 'ccccccc'
};
let userPool = new AmazonCognitoIdentity.CognitoUserPool(poolData);
