Unhandled exception when trying to restore to a group

[Mike Nguyen]

Running the following version of GYB on an up-to-date Ubuntu 22.04.04 LTS VM:

No issues backing mailboxes, but when I try to restore a mailbox to a Google Group (which does exist, etc.), I'm getting the following error:

mike@test-vm $ gyb --action restore-group --email us...@domain.com --service-account --use-admin mike-...@domain.com --local-folder ./GYB-GMail-...@domain.com
