Dompdf id givving ???

I installed this package.

I installed dompdf in my project. I want to export auth()->user() in laravel and I have a problem like this image.

Controller.php

use Barryvdh\DomPDF\Facade as PDF;

public function PDF()
{
    $pdf = PDF::loadView('load-pdf');
    $pdf->set_option('font-family', 'Tahoma');
    return $pdf->download('user.pdf');
}

load-pdf.blade.php

<!doctype html>
<html lang="fa" dir="rtl">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <link rel="stylesheet" href="{{ asset('css/bootstrap.min.css') }}">
