Version of docker-compose-yaml is unsupported

after editing yml file like suggested from comment above

version: '3.3'
services:
  db:
    image: mariadb:10.10
    restart: unless-stopped
    environment:
      MYSQL_RANDOM_ROOT_PASSWORD: "true"
      MYSQL_DATABASE: "passbolt"
      MYSQL_USER: "passbolt"

    volumes:
      - database_volume:/var/lib/mysql

  passbolt:
    image: passbolt/passbolt:latest-ce
    #Alternatively you can use rootless:
    #image: passbolt/passbolt:latest-ce-non-root
    restart: unless-stopped
    depends_on:

    ports:
      - 8081:80
      - 443:443

volumes:
  database_volume:
  gpg_volume:
  jwt_volume:

my result is:

ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?

If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
