CI4 Modules Code not work

One issue might be this line

Thank you, you are right. I added a namespace:

PHP Code:

//in controller
namespace Modules; //or namespace Modules/Node;

class Node extends \CodeIgniter\Controller
{
    public function index()
    {
        echo "Say Hi!";
    }
} 


and route:

PHP Code:

public $psr4 = ['Modules' => APPPATH.'modules']; //or APPPATH.'../modules' 


but psr4 still does not see files(my suggestion), because I found that syntax errors are not defined in /Modules

If you can show your code sample module, I can compare the changes made in these files and 100% determine my error.

P.S
Thanks guys, that drew attention to my problem!
