Mounting google-drive-ocamlfuse in a docker container

[sin3point14]

This isn't exactly related to this project, but I think you can help me with a problem I'm facing since it is similar :)

I am hosting a navidrome instance on my machine and mounting my google drive Music folder into it using google-drive-ocamlfuse. On the host, I can see my google drive folder contents, but the directory, when mounted into a docker container, is empty. I don't have experience with Linux FS stuff, but is this issue somewhat related to to PUID and PGID settings specified at https://github.com/mitcdh/docker-google-drive-ocamlfuse#environment-variables (navidrome container runs as root)? Also how can I got about debugging my issue?

What I did:

senpai@sinvps-reborn:~/navidrome$ mount --bind ./music ./music
senpai@sinvps-reborn:~/navidrome$ mount --make-shared ./music
senpai@sinvps-reborn:~/navidrome$ ls
Navidrome.tar.gz  data  docker-compose.yml  music
senpai@sinvps-reborn:~/navidrome$ google-drive-ocamlfuse -o allow_other -label me ./music/
senpai@sinvps-reborn:~/navidrome$ ls music
ls: reading directory 'music': Input/output error
'XXX.mp3'
"YYY.mp3"
'ZZZ.mp3'

I don't know why I get ls: reading directory 'music': Input/output error and docker.service doesn't contain and MountFlags statement.

My compose file:

 # This is just an example. Customize it to your needs.

version: "3"
services:
  navidrome:
    image: deluan/navidrome:latest
    security_opt:
      - seccomp:unconfined
    cap_add:
      - "MKNOD"
      - "SYS_ADMIN"
    devices:
      - /dev/fuse
    ports:
      - "4533:4533"
    environment:
      # Optional: put your config options customization here. Examples:
      ND_SCANSCHEDULE: 1h
      ND_LOGLEVEL: info
      ND_BASEURL: ""
    volumes:
      - "/home/sin3point14/navidrome/data:/data"
      - "/home/sin3point14/navidrome/music:/music:shared"

Edit: To debug ls: reading directory 'music': Input/output error I ran strace ls music and the entire log is available here https://controlc.com/966c4d54 while I found this to be particularly interesting:

close(3)                                = 0

Though after this, it still prints all the files

Asking on the astrada repo is best, this was just a quick implementation I put together to run the tool in Docker to avoid adding it to the host. Mounting with debug might get you more information.
