I have two gnome-shell extensions that don't appear to be loading after upgrading to 3.24. In gnome-tweak-tool they have a warning sign icon with "Error loading extension", and nothing else. I tried using looking glass (lg), and it just says "Error", and that the extension "has not reported any errors".
How can I debug the extension to find out why exactly it's not loading?
I found the error in the systemd journal:
$ sudo journalctl /usr/bin/gnome-shell
