Applescript rult to save email attachments into specific folder

I want to save the attachments that come from a specific email address into a folder, automatically.

I set up a rule that filters the emails correctly, and I tried using the script from this thread:

Using applescript to save email attachmen… - Apple Community

but it doesn't work, it doesn't save anything. Debugging it is so difficult! (any tips?)

A copy of the script I am using:

use AppleScript version "2.4" -- Yosemite (10.10) or later
use scripting additions


set attachmentsFolder to ((path to home folder as text) & "attacheds") as text


using terms from application "Mail"
	on perform mail action with messages these_messages for rule this_rule
		tell application "Mail"
			repeat with each_message in these_messages
				repeat with theAttachment in each_message's mail attachments
					set originalName to name of theAttachment
					set savePath to attachmentsFolder & ":" & originalName
					try
						save theAttachment in savePath
					end try
				end repeat
			end repeat
		end tell
	end perform mail action with messages
end using terms from
