Dzień dobry, mam problem. Robię kurs na Udemy z PHP i przy zadaniu z notatnikiem pojawia się błąd:
Warning: Undefined array key "created" in C:\xampp\htdocs\note\note\templates\pages\create.php on line 5 gdzie popełniam błąd?

require_once("src/Utils/debug.php");
require_once("src/View.php");
 
const DEFAULT_ACTION = 'list';
 
$action = $_GET['action']  DEFAULT_ACTION;
 
$view = new View();
 
$viewParams = [];
if ($action === 'create') {
  $page = 'create';
  $created = false;
 
  if(!empty($_POST)){
    $created = true;
    $viewParams=[
      'title' => $_POST['title'],
      'description' => $_POST['description']
    ]; 
 }
 
  $viewParams['created'] = $created;
 
} else {
  $page = 'list';
  $viewParams['resultList'] = "wyświetlamy notatki";

$view->render($page, $viewParams);
