laravel请求api出现500错误。

$api->get('user/register', 'AuthController@register');

路由里面用get方式从url获取参数

    public function register(Request $request)
    {
        $newUser = [
            'email' => $request->get('email'),
            'name' => $request->get('name'),
            'password' => bcrypt($request->get('password')),
        ];
        $user = User::create($newUser);
        $token = JWTAuth::fromUser($user);

        return response()->json(compact('token'));
    }
    
    
    {
