I am using the latest jj version with jj parralize

Parsing is a bit optimistic in some actions so it is expected to panic when something is off (e.g. output format of a command has changed).
I can fix it, but since I can't reproduce the error at the moment I might filter out something relevant.
Is this a public repo? Could you share the output of jj branch list --all?

Sorry I didn't see your reply until just now, my github notifications are very noisy. Looks like you managed to solve it without any more input from me, thanks! I really appreciate it.
