[Solved] Problem with ci4-adminlte

Hi everyone.
I hope you can help me with this problem.
I downloaded from github ci4 with adminlte3.
I noticed that, in the controller, if I put for example:
[code]
<? php namespace App \ Controllers;
use App \ Models \ UserModel;

class Users extends BaseController
{
    public $ uModel;

    public function __construct ()
    {
        helper ('form');
        $ this-> uModel = new UserModel ();
    }


    public function index ()
    {
        $ data ['users'] = $ this-> uModel-> findAll ();
        return view ('crud / index', $ data);
    }
}

[/ code]

It tells me that the "users" variable is undefined.

It seems to conflict with what is written in 'routes', ($ data).

I have tested it on another without adminlte and it works.
