use Weidner\Goutte\GoutteFacadeGoutte;


Route::get('/', function() {
    $crawler = Goutte::request('GET', 'http://duckduckgo.com/?q=Laravel');
    $url = $crawler->filter('.result__title > a')->first()->attr('href');

Your filterdid not return any results. That is why it crashed. That's how I solved this issue, by adding a try catch.

try {
   $url = $crawler->filter('.result__title > a')->first()->attr('href');
} catch (\InvalidArgumentException $e) {
    // Handle the current node list is empty..
}
