Crashes immediately with Gjs error about an undefined type object.

I'm on Arch Linux with GNOME 42.2 and I get the following error and exit trying to run it from the command line.

$ gnome-weather

(org.gnome.Weather:9846): Gjs-Console-CRITICAL **: 12:36:46.537: Error: Expected type object for argument 'boxed_type' but got type undefined _init/GObject.ParamSpec.jsobject@resource:///org/gnome/gjs/modules/core/overrides/GObject.js:404:24 @resource:///org/gnome/Weather/js/app/thermometer.js:47:32
