Those are the first line of multi-line journal messages, sent by
gnome-shell's javascript interpreter, most likely on the behalf of the
mentioned extensions. There might be more information in the later
part of the messages in your journal.

You can debug the extensions by starting GNOME Looking Glass, run it
by typing Alt-F2, type 'lg' and hit return.
