I had my scarpet repo placed under at ~/code/scarpet.
I wanted to beable to load app im developing without linking individual file or copying files for every change.
so i created a symlink folder of my repo ~/.minecraft/config/carpet/scripts/scarpet( symlink )

In game when i tried to load apps the suggester would pickup on the new scripts but when I ran the command they would fail to load.

script load script-in-symlink-folder
Faild to add script-in-symlink-folder app

My current work around is to move the actual repo into the carpet config path and create a symlink for my code folder.
and that is working fine.
