Files being written as root user instead of using PGID and PUID variables

[robflate]

I've set the env vars PGID and PUID to my local user but Bliss is saving cover art files as the root user.

How can I fix this? Thanks.

@robflate The problem still exists today but I have managed to "make an arrangement" by changing one line of the script "/bliss/bliss-runner.sh". The user created with the PGID and PUID passed is the user "abc":

franll@server: ~$ cat docker-compose.yml
...
build: bliss
  environment:
   - PUID=1100
   - PGID=1101
...

franll@server: ~$ docker exec -it bliss sh
root@bliss:/bliss# id abc
uid=1100(abc) gid=1101(abc) groups=1101(abc),1000(users)
root@bliss:/bliss#

Then, in the script I have changed "sh /bliss/bin/bliss.sh" for "su -s /bin/sh abc -c /bliss/bin/bliss.sh"

root@bliss:/bliss# cat /bliss/bliss-runner.sh 
# Script to restart bliss after an update
# Only needed for the Docker build, to stop the container exiting after an update
#
if [ ! -d /config/.java ] || [ ! -L /root/.java ]
then
  mkdir /config/.java
  ln -s /config/.java /root/.java
fi
while [ true ]
do
    #Modified by me
    su -s /bin/sh abc -c /bliss/bin/bliss.sh

    if [ "$?" = "0" ]; then
        echo "bliss.sh exited, restarting..."
        sleep 2
    else
        echo "bliss.sh exited with a non-zero value, exiting..."
        exit 1
    fi
done

And then Bliss is executed with the user abc:

root@bliss:/bliss# ps -aux

The abc user can create the config directory and add and edit the files:

root@bliss:/bliss# ls -ld /config/
drwxr-xr-x 6 abc abc 4096 Jul  7 21:00 /config/
root@bliss:/bliss# ls -l /music/
total 12
drwxrwxr-x 2 nobody abc 12288 Jul  7 21:02 'Various Artists - Gym Music 2023'
root@bliss:/bliss# ls -l /music/Various\ Artists\ -\ Gym\ Music\ 2023/

PD: Sorry if the answer is too long, I wanted to explain everything well.
