Estoy tratando de llamar a la función adminGetUser a través de AWS CognitoIdentityServiceProvider. La inicialización me parece bien, pero recibo el siguiente error.

 [Nest] 43 - 03/29/2022, 9:18:43 AM ERROR [ExceptionHandler] Cannot read properties of undefined (reading 'CognitoIdentityServiceProvider') TypeError: Cannot read properties of undefined (reading 'CognitoIdentityServiceProvider') at new UsersService (/usr/src/app/src/users/users.service.ts:21:36) at Injector.instantiateClass (/usr/src/app/node_modules/@nestjs/core/injector/injector.js:301:19) at callback (/usr/src/app/node_modules/@nestjs/core/injector/injector.js:48:41) at processTicksAndRejections (node:internal/process/task_queues:96:5) at Injector.resolveConstructorParams (/usr/src/app/node_modules/@nestjs/core/injector/injector.js:124:24) at Injector.loadInstance (/usr/src/app/node_modules/@nestjs/core/injector/injector.js:52:9) at Injector.loadProvider (/usr/src/app/node_modules/@nestjs/core/injector/injector.js:74:9) at async Promise.all (index 3) at InstanceLoader.createInstancesOfProviders (/usr/src/app/node_modules/@nestjs/core/injector/instance-loader.js:44:9) at /usr/src/app/node_modules/@nestjs/core/injector/instance-loader.js:29:13

Siguiendo este código:

 import AWS from 'aws-sdk'; import { Injectable } from '@nestjs/common'; import { Repository } from 'typeorm'; import { User } from 'models/user.entity'; import { CreateUserDto } from './dto/create-user.dto'; import { InjectRepository } from '@nestjs/typeorm'; @Injectable() export class UsersService { config = { apiVersion: '2016-04-18', region: 'eu-central-1', }; cognitoIdentity: AWS.CognitoIdentityServiceProvider; constructor( @InjectRepository(User) private usersRepository: Repository<User>, ) { this.cognitoIdentity = new AWS.CognitoIdentityServiceProvider(this.config); } async findByCognitoSub(cognitoSub: string): Promise<User | undefined> { const result = await this.usersRepository.find({ where: { cognitoSub } }); if (result.length !== 1) { return undefined; } return result[0]; } getUser(userPoolId: string, userName: string) { return this.cognitoIdentity.adminGetUser({ UserPoolId: userPoolId, Username: userName, }); }

¡Cualquier ayuda sería muy apreciada!
