PDF shortcut

Am I the only one drawing a blank on generating PDFs through scripts, quick actions, shortcuts, etc? There's very rarely any error message; it just does ... nothing. Press the keyboard shortcut, right-click the script or action in the context menu, etc --> nothing happens and I can't find a new PDF file anywhere. Time was when this function was one of best things about macs.

To be clear: printing to PDF through the print menu / command from within an app, that works the same as always. Likewise those Apple apps that have an "Export as PDF .." file menu command, that works nicely too. But no show with any form of Finder-based script or action.

Are others encountering this? Any thoughts?
