Need help creating Pika Backup snap (borgbackup issue)

I’ve been hacking together a snap for Pika Backup here: GitHub - thatLeaflet/pika-backup-snap: unofficial Picka Backup snap. It’s based on core24, but I have the same issue on core22 too.

I’m able to run the app, but I’m running into an issue with borgbackup, the backend that Pika Backup uses. In the log, I see

(pika-backup:415381): pika-backup-WARNING **: 18:08:41.929: src/ui/ Displaying error:
  Failed to run “borg”. Is BorgBackup installed correctly?
  Io(Os { code: 2, kind: NotFound, message: "No such file or directory" })

I do have borgbackup in my stage-packages. When I run snap run --shell pika-backup and then borg, I get this back

Traceback (most recent call last):
  File "/usr/lib/python3.12/importlib/metadata/", line 397, in from_name
    return next(

During handling of the above exception, another exception occurred:
