UPID and Node value don't match regex pattern when Verifying through GUI

Hello,

I am having a PBS instance in a docker container on my Synology NAS based off this GitHub project : https://github.com/ayufan/pve-backup-server-dockerfiles/
I know it is not recommended, but given my current setup it's the only way I could find to make it work...

Now onto my issue:


Backups work great, but when I try to run a verification job is where it fails. For the record, I am using the GUI.

If I click on "Verify" on one of the backups of a container, I have the popup "Task viewer" that opens, "Output" tab stays empty, and if I look at the Status I have this : 1777898590104.png

I tried to do some research and look at the underlying API call and I see that the API is trying to reach: /api2/json/nodes/<REDACTED>/tasks/UPID%3A<REDACTED>%3A0000000A%3A04D24784%3A0000001F%3A69F891E0%3Averify_group%3Abackup%5Cx3a-ct-100%3Aadmin%40pbs%3A/status


Looking online, I found this that seems to be a similar issue : https://forum.proxmox.com/threads/pbs-api.154610/

However, this user is using the API through CLI, and I'm not.
I am unsure if there is a workaround for me, or if it's an issue caused by my setup and I should just forget about using the Verify job.

Thanks for your help !

What version of PBS are you running? Just double checked with an up to date version, but I could not trigger the issue you are seeing. The docker image you linked to seems to be unmaintained, so probably not what you want to use in the long run.
