Solution:

The above issue is occured due to the DependencyInjection. In order to fix this issue follow the below instructions,

Creating an Extension Class:

1. It has to live in the DependencyInjection namespace of the bundle;
2. It has to implement the ExtensionInterface, which is usually achieved by extending the Extension class;
3. The name is equal to the bundle name with the Bundle suffix replaced by Extension (e.g. the Extension class of the AcmeBundle would be called AcmeExtension and the one for AcmeCatalogBundle would be called AcmeCatalogExtension).

Code:

# /src/Acme/Bundle/CatalogBundle/DependencyInjection/AcmeCatalogExtension.php
`<?php

namespace Acme\Bundle\CatalogBundle\DependencyInjection;

use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Loader;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;

class AcmeCatalogExtension extends Extension
{
public function load(array $configs, ContainerBuilder $container)
{
$loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
$loader->load('entities.yml');
}
}`

Let me know if you have any questions
