I am using a workflow for Alfredapp that permits me to open files in PDF Expert rather than Acrobat. There is a conflict. Quitting KBM allows the workflow to do its job. Running KBM produces this debugging error:
[10:06:56.110] Logging Started...
[10:07:27.337] Open with PDF Expert[Script Filter] Queuing argument '(null)'
macos 26.5.2
alfred app 5.7.3
Is there anyway to determine what in KBM is interfering with the workflow? More discussion here:
That's a clue but you didn't give us much to go on. Still, I'll take a wild guess: you're not quoting a filename whose path has spaces in it as an argument to PDF Expert.
