Error getting internal id

So I noticed these errors when installing but thought it had something to do with snapshots (because I was trying to get that working) but thought it got fixed when I got the snapshots working (kinda).
Was just looking through the logs and noticed the error had NOT gone away.
Backups seems to be working though, no errors server side.

It does this every backup.

$ journalctl -u urbackupclientbackend.service -e

$ id -un 110
plex
$ id -un 111
deluge
$ id -g deluge
117

If I try to “id -gn 117” it actually tells me “id: ‘117’: no such user”, but all seems correct if I use getent or above commands, just thought I should mention it.

2 directories are being backed up, “usr” and “diverse”.
usr is btrfs, snapshot is being used, no mentions in logs.

diverse is ext4, snapshot mechanism is disabled (I think, at least I don’t get errors serverside now, posted about the process in the forum here). Maybe this has something to do with it?

Please advice.
