Container can see all media files, but Jellyfin does not

[SaladCesar]

Hi,

I am using docker. Here is my setup:

  jellyfin:
    image: jellyfin/jellyfin:latest
    container_name: jellyfin
    environment:
      PUID: 1000
      PGID: 1000
      TZ: ${TZ}
      JELLYFIN_PublishedServerUrl: https://stream.${DOMAIN}
    networks:
      services:
    volumes:
      - ${CONFIG_FOLDER}/jellyfinconfig
      - ${FILMS}media/films:ro
      - ${SERIES}media/series:ro
      - ${MUSIQUE}media/musique:ro
      - ${LIVRES}media/livres:ro
      - ${TROISD}media/troisd:ro
      - ${BONUS}media/bonus:ro
      - ${SHORTS}media/shorts:ro
    restart: unless-stopped
    devices:
      - /dev/dridev/dri
      - /dev/kfddev/kfd

I am trying to add a library from the folder /media/films. When I log into the container console, I can cd into /media/films, and list all files and their content. The container seems to have correctly access to the files. But when in Jellyfin itself, I don't have access. Then trying to add /media/films as a library, I have the following error:

[21:32:30] [ERR] [11] Jellyfin.Api.Middleware.ExceptionMiddleware: Error processing request: Could not find a part of the path '/media/films'. URL GET /Environment/DirectoryContents.

I don't understand why Jellyfin can't access the files if the container has correct access.

Could you help me ?
Thankd in advance for any answer
