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

            ->where(
                'created_at',
                '>=',
                Carbon::now()->subSeconds(config($rule))
            )
            ->exists();
    }
