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.
 
Bit late on the answer, apologies...

Just updated the container to its latest release, using PBS version 4.2.0 and the issue is still there.

I will keep at it without using Verify and we will see if eventually something in the future fixes the issue...
