App.config is not a function error

[j0sko]

Running ags throws

(com.github.Aylur.ags:8995): Gjs-WARNING **: 10:22:08.784: JS ERROR: TypeError: App.config is not a function
@file:///home/j0sko/.config/ags/config.js:10:5
_init/GLib.MainLoop.prototype.runAsync/</<@resource:///org/gnome/gjs/modules/core/overrides/GLib.js:266:34

Here is the code, copied from wiki:

const myLabel = Widget.Label({
    label: 'some example content',
});
const myBar = Widget.Window({
    name: 'bar',
    anchor: ['top', 'left', 'right'],
    child: myLabel,
});

App.config({ windows: [myBar] });

I used the arch package if it is relevant (not built from source)

your ags is out of date, App.config was added quite recently you can use the old version

export default {
  windows: [myBar]
}
