You need to do this (based on previous answer):

public function getAllCategoryAction() {
    $em = $this->getDoctrine()->getManager();
    $query = $em->createQuery(
        'SELECT c
        FROM AppBundle:Categoria c'
    );
    $categorias = $query->getArrayResult();

    $response = new Response(json_encode($categorias));
    $response->headers->set('Content-Type', 'application/json');

    return $response;
}

It works perfect with any Query that Doctrine returns as array.
