installPlugin with resource set to git:directory and path fail with "Invalid PACK header"

[ocean90]

I tried the example from here to install my plugin via a git checkout but it failed to load:

This was the version: ocean90/public-post-preview@e6106fb

After searching a bit I found this comment by @adamziel and also set the path to /, see ocean90/public-post-preview@fab7d28. Now the installation went through (Playground link) but I get a 404 error for the assets in the block editor:

GET https://playground.wordpress.net/scope:energetic-cozy-park/wp-content/plugins/js/dist/gutenberg-integration.js?ver=6.7 net::ERR_ABORTED 404 (Not Found)

So in ocean90/public-post-preview@8ed2a8e I tried path set to /public-post-preview and now I get the "Invalid PACK header" error again.

What value do I have to use for path?
