I am currently learning JamfPro

Oh, I follow now. Looks like that video has not been updated in 7 years. Jamf is pretty bad about tech debt, they will make one of these videos and never review it again.

Looks like Jamf Moved the scripting resources to GitHub. GitHub - jamf/Jamf-Nation-Scripts: Scripts Migrated from Jamf Nation

Thank you.
