Folder Actions - Monterey - not working

Hi all - I have several Folder Action Scripts which I’ve been successfully using on Mojave.
I’ve upgraded to a new MBP using Monterey and transferred these over with all the relative paths and ref’s updated etc.

These simply will not action at all.
Has something changed with the way Monterey interprets Applescript?

Below is one of the less complex scripts which simply moves a PDF when it has been distilled and appears in a watched “out” folder to another folder which has a subsequent action on it (that also does not work).



on adding folder items to thisFolder after receiving DroppedFiles
	delay 0.2
	tell application "Finder"
		set a to "Macintosh HD:Users:g-uk-tam1-retail-2:Desktop:PDF's:DISTILLED FOR RELEASES:Out:" as alias
		set b to "Macintosh HD:Users:g-uk-tam1-retail-2:Desktop:PDF's:FOR RELEASES:" as alias
		
		move files of entire contents of a to b with replacing
	end tell
	
end adding folder items to



Any pointers greatly received.

Many thanks

First, you could use
(Path to desktop folder as text)

Second, check your security settings in system preferences - maybe you’ve to authorize first “folder action setup”

Oh, it seems monterrey still supports Applescript
