Error: parameter verification failed - 'upid': value does not match the regex pattern

I'm running this docker:

docker run -d \
  --name=pbs \
  --network=host \
  --tmpfs /run \
  -v /volume1/homes/pbs/datastore:/datastore \
  -v /volume1/homes/pbs/docker/etc:/etc/proxmox-backup \
  -v /volume1/homes/pbs/docker/logs:/var/log/proxmox-backup \
  -v /volume1/homes/pbs/docker/lib:/var/lib/proxmox-backup \
  ayufan/proxmox-backup-server

inside on Synology DSM 7.2.2 on a DS220+ (uname - gives Linux Storage_DS220 4.4.302+ #72806 SMP Thu Sep 5 13:44:44 CST 2024 x86_64 GNU/Linux).

When running proxmox-backup-manager prune-job run default inside the container, I get this: Error: parameter verification failed - 'upid': value does not match the regex pattern. Trying the run from the web interface gives me this:

Backups are all running fine, but I can't prune or garbage collect. Any ideas how to fix this?

I moved to PBS running in a VM on my NAS. Because the issue is still relevant I will keep this issue opened, but my problem is solved.
