Just a friendly reminder: changeWidgetSetting
on post-avatar is a deprecated API and will be removed soon.
Maybe you should change your code to this
import { apiInitializer } from "discourse/lib/api";
export default apiInitializer((api) => {
const site = api.container.lookup("service:site");
if (!site.mobileView) {
api.modifyClass("component:post/avatar", (SuperClass) => class extends SuperClass {
get size() { return "70"; }
});
}
});
