Почему в __construct перестал определятся аутентифицированный пользователь?

class PostController extends BaseController
{
    protected $auth;

    public function __construct()
    {
        parent::__construct();
        
        $this->middleware(function ($request, $next) {
            $this->auth = Auth::user()->auth;

            return $next($request);
        });
}
 public function index()
    {
        // $this->auth = Auth::user();
        dd($this->auth);

<?php

namespace App\Http\Controllers;

use App\User;
use Illuminate\Support\Facades\Auth;
use App\Http\Controllers\Controller;

class ProjectController extends Controller
{
    /**
     * All of the current user's projects.
     */
    protected $projects;

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware(function ($request, $next) {
            $this->projects = Auth::user()->projects;

            return $next($request);
        });
    }
}
