Node.js LoopBack framework, docker -compose.yml, MongoDB Connector - Ошибка: MongoServerSelectionError: connect ECONNREFUSED

Я не могу подключить MongoDB к моей платформе LoopBack.

Я могу подключиться к базе данных с Пн go Express. Я могу создавать БД и коллекции. Но он работает на локальном хосте. Из моего приложения мне нужно соединиться с mon go: 27017.

docker -compose.yml 

version: "3.7"
services:
  web:
    build:
      context: .
      dockerfile: .docker/node/Dockerfile
    volumes:
      - .:/home/node/app
    ports:
      - 3000:3000
    depends_on:
      - mongo
    links:
      - mongo
  mongo:
    image: mongo:latest
    restart: always
    volumes:
      - ./src/datasources/mongodb:/data/db
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example
    ports:
      - 27017:27017
  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example

Может кто-нибудь помочь, пожалуйста? :)

ОБНОВЛЕНИЕ: я решаю свою проблему с добавлением сетей в мой docker-compose.yml

networks:
  app-tier:
    driver: bridge
  me-tier:
    driver: bridge
