I have a strange issue with a QuickLook generator I'm building for Google Drive.
The "*.gdoc" files on my computer have a UTI of be.gdoc.quicklook as shown by running mdls -name kMDItemContentType /Volumes/GoogleDrive/My\ Drive/*.gdocin terminal
And my QL generator qlmanage -m correctly shows that be.gdoc.quicklook -> /Users/itai/Library/QuickLook/GoogleDriveGenerator.qlgenerator
Moreover, when I run qlmanage -p -c "be.gdoc.quicklook" some_file.gdoc I get the correct preview of the file contents using the generator
But when I run qlmanage -p some_file.gdoc my custom generator isn't invoked. Likewise, when I press spacebar in finder my custom generator is not invoked
$ qlmanage -p dummy.gdoc
Testing Quick Look preview with files:
dummy.gdoc

The permission denied error is not related in my opinion because in the -c case everything works. Moreover, qlmanage -p some_picture.jpeg also shows that permission denied error, so it seems to be an error that shows up even for System plugins.
Please note that this same plugin worked just fine on Mojave. Note also that I have other custom QL plugins that seem to work just fine on their respective UTI files
