1. Please remove `schemas/gschemas.compiled`. Not needed for 45+ packages. 2. In 42+ you have `connectObject()` and `disconnectObject()`. No need to use manual clean up: [Port Guide 42: Signals](https://gjs.guide/extensions/upgrading/gnome-shell-42.html#signals) For example: ```js this._settings.connectObject('changed::update-interval', () => { this._restartTimer(); }, this); ``` On destroy: ```js this._settings.disconnectObject(this); ```
