Incorrect error "Application folder /app and Data folder /data are shared" - volume subpath issue?

[scottjamesrogers]

Recently the application stopped working. The container still starts fine but the logs report:

Application folder /app and Data folder /data are shared. Please fix this.

The configuration has not changed, and the application was working correctly without issue previously. The /app and /data folder are not shared.

The image is deployed using the following compose config:

volumes:
  roon:

services:
  roon:
    image: steefdebruijn/docker-roonserver:latest
    container_name: roon
    hostname: roon
    restart: unless-stopped
    volumes:
      - type: volume
        source: roon
        target: /data
        volume:
          subpath: data
      - type: volume
        source: roon
        target: /app
        volume:
          subpath: app
      - type: volume
        source: roon
        target: /backup
        volume:
          subpath: backup
      - ${MEDIA_DATA_ROOT}/library/music:/music:ro
    environment:
      - TZ=${TIMEZONE}
    network_mode: host

I assume this is due to the use of volume subpaths in my compose file. Is there a recent update that could have changed the way this validation check is being performed?
