Symfony classNotFoundInNamespaces exception - symfony

Question

I am working with a bundle called rss-atom-bundle. Through this bundle I should be able to fetch the RSS feeds and save them to the database.
I can get the bundle to work up till getting the feeds from the URL but when I try to presist I get the following error and I just cant figure it out why I am getting it.
The class 'Debril\RssAtomBundle\Protocol\Parser\Item' was not found in the chain configured namespaces Symfony\Bundle\AsseticBundle\Entity, AppBundle\Entity`
Looking online and at stackoverflow i came across questions that were related to this but all of them are talking about by default the Entity should be inside the Entity folder of the Bundle and if they are not then this error appears but my Entity files are inside Entity folder and I followed the instructions given by the bundle author but still i cant get passed this error
This is what my Controller looks like
$em = $this->getDoctrine()->getManager();
// fetch the FeedReader
$reader = $this->container->get('debril.reader');
// this date is used to fetch only the latest items
$unmodifiedSince = '01/01/2000';
$date = new \DateTime($unmodifiedSince);
// the feed you want to read
$url = 'http://example.com/feed/';
$feeds = $reader->getFeedContent($url, $date);
$items = $feeds->getItems();
dump($items);
foreach ( $items as $item ) {
$em->persist($item);
}
$em->flush();
As per bundle instructions I did implement FeedInterface to my Feed Entity and ItemInInterface, ItemOutInterface to my Item Entity
This is what my orm.yml looks like for Feed and Item Entity
Feed
AppBundle\Entity\Feed:
type: entity
table: null

Any help will be really appreciated as I am clueless why i am getting the error?

Try to add RssAtomBundle to the list with mappings in app/config/config.yml
orm:
entity_managers:
default:
connection: default
mappings:
AppBundle: ~
AsseticBundle: ~
RssAtomBundle: ~
