job-id: invalid format - invalid configuration ID

[automaton]

Ever since I updated to 8.2.5, I've been getting the following error in my log when my backup jobs are supposed to run once a week:

Sep 28 01:00:09 pve pvescheduler[117971]: 400 Parameter verification failed.
job-id: invalid format - invalid configuration ID 'b61e26046051f94aef2862d364520ad621e35710:1'
Sep 28 01:00:09 pve pvescheduler[117971]: jobs: encountered object '400 Parameter verification failed.
job-id: invalid format - invalid configuration ID 'b61e26046051f94aef2862d364520ad621e35710:1'


', but neither allow_blessed, convert_blessed nor allow_tags settings are enabled (or TO_JSON/FREEZE method missing) at /usr/share/perl5/PVE/Jobs.pm line 228.

I've only ever used the UI to create backup jobs on the data center, never the command line, so I don't understand how this could happen, or how I can fix it.

If I run the backup job manually it works fine with this log:

Any ideas what's going on here or how to fix it? Thanks.
