Problem in Filter

Ihave code in Filter like this

PHP Code:

<?php

namespace App\Filters\API;

use CodeIgniter\Filters\FilterInterface;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use Config\Services;

class GuestRequest implements FilterInterface
{
    public function before(RequestInterface $request)
    {

         //$req  = ( $request->getMethod()=='post' && $request->isAJAX() == TRUE$
        $req = $request->getMethod();
        $ajx = $request->isAJAX();

        if( $ajx == true )
        {
                Config('App')->data = (object)[$req, $ajx];
                Config('App')->time = microtime(true);
                return true;

        }


        return Services::response()
            ->setStatusCode(401);

    } 


In local (OS : linix mint, php 7.2) run normal
in VPS (OS Centos, php 7.2)
always return 401, although my codes change to
if( $ajx == false)

I think you've already solved that. But if a Response instance is returned the request will be responded.

Oh, it looks like you can not return anything not empty. Even then the code should not be executed... Have you found a solution?
