[Docker] Unsupported config option for services.app:'node'

When I was making a docker environment construction and entered a command to initialize npm, an Error occurred.

#docker-compose run --rm node npm init
ERROR: The Compose file './../docker-compose.yml' is invalid because:
Unsupported config option for services.app: 'node'

Looking at the contents of this Error, it seems that an Error has occurred around'node'in the docker-compose.yml file. .. ..

When I checked the relevant part of the yml file, "services-> node" was originally correct, but the indent was shifted to "services-> app-> node". .. ..

Mistake ↓

version: '3'
services:
  app:
    image: nginx:latest
    container_name: "app"
    ports:
      - "8080:80"
    volumes:
      - ./src/html:/app
      - ./docker/nginx/default.conf:/etc/nginx/conf.d/default.conf
    node:
      image: node:10
      container_name: node
      tty: true
      working_dir: /usr/src/app
      volumes:
       - ./src:/usr/src/app

Correct ↓
