Crash on save_folders.py

[GitBytes]

Version Affected: 1.1.6
Environment: Kubernetes

Background:
Been using the tool successfully for a while but backups recently started failing with the following Traceback information:

Traceback (most recent call last):

Seems to be related to the stage Save Folders. Any thoughts on what might be happening or what this traceback might be indicating beyond just not returning the expected JSON (i.e. None)?

Thanks!
