Warning: strpos() expects parameter 1 to be string, object given when calling doctrine's getRespository() method

Question

Just passing the class name to getRepository() method

/**
 * @Rest\Route("/batches", name="isbn_list_batches", methods={"GET"})
 * @Rest\QueryParam(name="page", default=1, requirements="\d+")
 * @Rest\QueryParam(name="limit", default=10, requirements="\d+")
 *
 * @param ParamFetcher $fetcher
 * @return \Pagerfanta\Pagerfanta
 */
public function listAction(ParamFetcher $fetcher)
{
    return $this
        ->em->getRepository("App:Batch")
        ->createPaginator(
            (int)$fetcher->get('page'),
            (int)$fetcher->get('limit')
        );
}

It was working and now is throwing that error. I also tried using getRepository(Batch::class)

If you're using a custom query builder for the ->createPaginator() function, try to add ->getQuery() at the end of it. So for example:

createQueryBuilder()->('bla bla bla')->getQuery();

Otherwise please provide a dump by doing:

dd($this->em->getRepository(Batch::class)->findAll());
