        'title' => $this->title,
        'content' => $this->content,
        'isFree' => (boolean)$this->free,
    ];
}

修改控制器：app/Http/Controllers/LessonsController.php

public function index()
{
    $lessons = Lesson::all();
    $data = [
        'list' => $lessons,
    ];
    return response()->json($data)->setStatusCode(200);
}
