Problem with SDK amazon-cognito-identity-js

Question

我从AWS-Cognito开始。我已经在Amazon平台上创建了一个用户池和一个UserPoolClient。我正在实施执行用户注册的lambda(作为测试(。但是，尝试使用邮递员返回"内部服务器错误"来运行它。这是我的lambda的代码。

module.exports.register = async event => {
  var AmazonCognitoIdentity = require('amazon-cognito-identity-js');
  var CognitoUserPool = AmazonCognitoIdentity.CognitoUserPool;
  var poolData = {
    UserPoolId: '...', // Here, I put my UserPoolId
    ClientId: '...' // Here, I put my ClientId
  };
  var userPool = new AmazonCognitoIdentity.CognitoUserPool(poolData);
  var attributeList = [];
  var dataEmail = {
    Name: 'email',
    Value: '[e-mail]'
  };
  var dataPhoneNumber = {
    Name: 'phone_number',
    Value: '[phone]'
  };
  var attributeEmail = new AmazonCognitoIdentity.CognitoUserAttribute(dataEmail);
  var attributePhoneNumber = new AmazonCognitoIdentity.CognitoUserAttribute(dataPhoneNumber);
  attributeList.push(attributeEmail);
  attributeList.push(attributePhoneNumber);
  var cognitoUser = ''
  userPool.signUp('[e-mail]', 'MyPassword7.com', attributeList, null, function (err, result) {
    if (err) {
      cognitoUser = err;
    }
    cognitoUser = result.user;
  });
  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'Go Serverless v1.0! Your function executed successfully!',
        input: event,
        cognitoUser: cognitoUser
      },
      null,
      2
    ),
  };

我认为您需要在响应中添加适当的标题

      headers: {
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Credentials': true,
        'Content-Type': 'application/json',
      },
