Dragging files don't show up in destination

[patheros]

So I've got an audio plugin that is using node-appdmg to create a mac installer. But when dragging the files over into the destination folders, the files do not actually get copied and no warning is given. Any insight into what might be causing this or ideas on how to debug this would be helpful.

The files can be found here https://github.com/patheros/JUCE-plugin-test2/actions/runs/4331288750

The system specs:

Here is the dmg file, incase the above link has expired.
