Applescript - Getting Property of an Object Not Working The dictionary for Messages states that the application has a "chat" element which has the property "updated". My goal is to get this property, and here is my code:

tell application "Messages"
    set _chat_ to get first chat
    set _date_ to updated of _chat_
end tell


When I run this, I get the error:

Messages got an error: Can’t get updated of text chat id "iMessage;-;+&lt;someone's phone number&gt;".


This seems like a very basic thing, and yet it doesn't work. What am I doing wrong?
This does not work because the AppleScript support in Messages.app is broken.
