Solution 1:[1]

  1. invalid namespace App or directory structure, read PSR-4 manualto understand how it use
  2. redundant import use App\*; in CatalogController.php - this classes in App namespace too
  3. invalid JSON "App\"
  4. redundant classmap section in composer.json - read Composer manual to understand how it use
