Get name of chat - error -1728


I am trying to make a AppleScript getting chat names from messages or ichat.

However, I keep getting error -1719 for the entire script and -1728 for the individual elements - how do I avoid that?

Script Debugger has full disk access - what is missing?

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

use scripting additions

tell application id "" -- Messages
	tell its chat 1
	end tell
end tell

The issue is with itself. I wouldn’t be surprised if it’s a deliberate change in the name of security.

Okay - can I change any thing to help the process?

No, unfortunately. Messages scripting looks like something that is going away.
