Leantime breaks on non-default user

[klevvit]

Successful run with default settings, but can't make leantime work with set user: directive.

Steps to reproduce

1. Clone repo

    git clone https://github.com/Leantime/docker-leantime.git 
    cd docker-leantime 
    cp sample.env .env

2. Modify files:
   docker-compose.yml - add user: 1906:1906 to leantime: service
   .env - set 1906 for PUID and PGID

Just in case, 1906 is an existing user & group I created before:
sudo useradd --no-create-home --shell /usr/bin/nologin --uid 1906 leantime (using Arch, btw)

3. Finally, run
   docker compose up -d && docker compose logs -f

docker compose logs

I tried different methods to fix this issue, none were successful yet. Even container build with PUID=1906 & PGID=1906 args didn't help, though got not the same errors.
