我试图在邮递员上得到答复，但它给了我500 Internal Server Error

Question

<?php

namespace App\Http\Controllers;

use App\Model\question;
use Illuminate\Http\Request;

class QuestionController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
       return question::latest()->get;
    }

这是我的控制器

<?php

Route::apiResource('/question','questioncontroller');

这是我的api.php
