Uncaught PHP Exception Symfony\Component\Debug\Exception\ClassNotFoundException HELP

[PMunoz92]

Hello, I need some help, I've following PS1.7 Documentation with no successful results

I'm trying to do this

 

And getting this

 

This is my foo.php file:

<?php
// foo.php
/* ... */
/**
 * Module installation.
 *
 * @return bool Success of the installation
 */
if (!defined('_PS_VERSION_')) {
    exit;
}
class Foo extends Module
{
    public function __construct()
    {
        $this->name = 'foo';
        $this->tab = 'front_office_features';
        $this->version = '1.0.0';
        $this->author = 'Patricio Munoz';
        $this->need_instance = 0;
        $this->ps_version_compliancy = array(
            'min' => '1.6',
            'max' => _PS_VERSION_,
        );

        parent::__construct();

        $this->displayName = $this->l('Dumping products Module');
        $this->description = $this->l('Display an array of products');

        $this->confirmUninstall = $this->l('Are you sure you want to uninstall?');

        $this->install();
    }
    public function install()
    {
        if (Shop::isFeatureActive()) {
            Shop::setContext(Shop::CONTEXT_ALL);
        }

        if (!parent::install() ||
            !$this->registerHook('displayDashboardToolbarIcons')
            //!$this->registerHook('displayDashboardTop')
        ) {
            return false;
        }

        return true;
    }

    public function uninstall()
    {
        return parent::uninstall();
    }

/**
 * Add an "XML export" action in Product Catalog page.
 *
 * @return bool Success of the installation
 */
    public function hookDisplayDashboardToolbarIcons($hookParams)
    {
        if ($this->isSymfonyContext() && $hookParams['route'] === 'admin_product_catalog') {
            $products = $this->get('product_repository')->findAllByLangId(1);
            dump($products);
        }
    }

    // public function hookDisplayDashboardTop($hookParams)
    // {
    //     if ($this->isSymfonyContext() && $hookParams['route'] === 'admin_product_catalog') {
    //         $products = $this->get('product_repository')->findAllByLangId(1);
    //         dump($products);
    //     }
    // }
}

This is my services.yml

# modules/foo/config/services.yml

services:
    _defaults:
        # automatically injects dependencies in your services
        autowire: true
        # automatically registers your services as commands, event subscribers, etc.
        autoconfigure: true
        # this means you cannot fetch services directly from the container via $container->get()
        # if you need to do this, you can override this setting on individual services
        public: true
    product_repository:
        class: Foo\Repository\ProductRepository
        arguments: ['@doctrine.dbal.default_connection', '%database_prefix%']
# services:    
#     Foo\Repository\:
#         resource: '../../src/Repository/*'
#         public: true

and this is my ProductRepository.php file:

<?php
// src/Repository/ProductRepository.php
namespace Foo\Repository;

use Doctrine\DBAL\Connection;

class ProductRepository
{
    /**
     * @var Connection the Database connection.
     */
    private $connection;

    /**
     * @var string the Database prefix.
     */
    private $databasePrefix;

    public function __construct(Connection $connection, $databasePrefix)
    {
        $this->connection = $connection;
        $this->databasePrefix = $databasePrefix;
    }

    /**
     * @param int $langId the lang id
     * @return array the list of products
     */
    public function findAllbyLangId(int $langId)
    {
        $prefix = $this->databasePrefix;
        $productTable = "${prefix}product";
        $productLangTable = "${prefix}product_lang";

        $query = "SELECT p.* FROM ${productTable} p LEFT JOIN ${productLangTable} pl ON (p.`id_product` = pl.`id_product`) WHERE pl.`id_lang` = :langId";
        $statement = $this->connection->prepare($query);
        $statement->bindValue('langId', $langId);
        $statement->execute();
        
        return $statement->fetchAll();
    }
}

this is my directory tree:

foo
├── config
│   └── services.yml
├── foo.php
└── src
    └── Repository
        └── ProductRepository.php

I hope someone can help me, thanks
