Debug is breaking my JSON... How to disable it from some methods ?

I tried to do that... as stated in the userguide....

But it didn't work... I had to change the CI_DEBUG variable in Boot/development.php

PHP Code:

<?php namespace Config;

use CodeIgniter\Config\BaseConfig;

class Filters extends BaseConfig
{
    // Makes reading things below nicer,
    // and simpler to change out script that's used.
    public $aliases = [
        'csrf'     => \CodeIgniter\Filters\CSRF::class,
        //'toolbar'  => \CodeIgniter\Filters\DebugToolbar::class,
        'honeypot' => \CodeIgniter\Filters\Honeypot::class,
    ];

    // Always applied before every request
    public $globals = [
        'before' => [
            //'honeypot'
            // 'csrf',
        ],
        'after'  => [
            //'toolbar',
            //'honeypot'
        ],
    ];

    // Works on all of a particular HTTP method
    // (GET, POST, etc) as BEFORE filters only
    //     like: 'post' => ['CSRF', 'throttle'],
    public $methods = [];

    // List filter aliases and any before/after uri patterns
    // that they should run on, like:
    //    'isLoggedIn' => ['before' => ['account/*', 'profiles/*']],
    public $filters = [];
} 


PHP Code:

/*

  | DEBUG MODE
  |--------------------------------------------------------------------------
  | Debug mode is an experimental flag that can allow changes throughout
  | the system. This will control whether Kint is loaded, and a few other

defined('CI_DEBUG') || define('CI_DEBUG', 0);
