Error must take exactly 2 arguments - PHP / Wordpress / visual composer

Hello, I'm trying to create a custom component for visual composer a dropdown, I have the php file search.php that creates the custom component, and I have the file Recipe.php that returns the data to be displayed in the component, the problem is that when I run the page does not appear the component nor the data of the file Recipe.php.

From the DEBUG of Wordpress it presents the following message below:

 [03-Feb-2018 02:33:07 UTC] PHP Fatal error:  Method ImmutableValueObject::__set() must take exactly 2 arguments in /var/www/html/wp-content/themes/n2go-2014/visual-composer/elements/Receita.php on line 33

Finally follows the contents of the mentioned PHP files:

Search.php

    <?php
include 'Receita.php'; 

class Pesquisa extends WPBakeryShortCode
{  

}

$atts = Integration::instance()->get_default_shortcode_attrs();
vc_map([
    'name' => __('N2Go Integrations', 'js_composer'),
    'base' => 'n2go_integrations',
    'icon' => 'icon-heart',
    'category' => [__('Content', 'js_composer')],
    'params' => array_map(


        function($key, $default){
            return [
                'type' => 'Dropdown',
                'heading' => ucwords(str_replace('_', ' ', $key)),
                'param_name' => $key,
                'value' => $default,

        },
        array_keys($att),
