Accessing id on the interface Illuminate\Contracts\Auth\Authenticatable suggest that you code against a concrete implementation. How about adding an instanceof check?

        $links = new Link;
        $links->link = $link;
        $links->user_id = $userId;
        $links->title = $icon;
        $links->button_id = '94';
        $links->save();
        $links->order = ($links->id - 1);
        $links->save();
    }

    private function updateIcon($icon, $link)
    {
        Link::where('id', $this->searchIcon($icon))->update([
            'button_id' => 94,
            'link' => $link,
            'title' => $icon
        ]);
    }
