“Response内容必须是实现__toString（）的字符串或对象，”boolean“给出。”

我正在尝试使用AJAX json检索记录，并且我正在尝试通过JSON格式将结果数据发送回客户端。 （以下是我的尝试）

$vote = users_details::where('vote', '=', 1)->get();
return response()->json(['success' => true, 'vote' => $vote ]);

但不幸的是，遗憾的是没有工作，它让我犯了这个错误。

  

“Response内容必须是实现的字符串或对象   __toString（），“boolean”给出。“

我试过

dd(var_dump($vote));

它向我显示检索到的数据，所以我猜问题是在返回JSON部分，我甚至尝试过

$vote = users_details::where('vote', '=', 1)->get()->toJson();
return response()->json(['success' => true, 'vote' => $vote ]);

并且它抛出了这个错误（参见下文）

  

调用未定义的函数App \ Http \ Controllers \ toJson（）

任何想法，帮助，建议，推荐，线索好吗？

更新：使用

检索的数据 
dd(var_dump(users_details::where('vote', '=', 1)->get(['firstname', 'middlename', 'lastname', 'branch', 'position', 'img'])));

结果
