Rest API using Symfony4

Question

I have been creating REST API using symfony4, I have installed FosRestBundle and I configured it to return object directly from the controller.

I want to return an object from the controller but I get the error

Warning: ReflectionObject::__construct() expects parameter 1 to be object, null given

MoviesController:

/**
 * @Rest\View()
 * @Route("/movies", name="get_movies")
 *
 */
public function getMovies()
{
    $movies = $this->getDoctrine()
                    ->getRepository(Movie::class)
                    ->findAll();

    return $movies;

 }

fos_rest.yaml:

fos_rest:
    param_fetcher_listener: force
    body_converter:
        enabled: true
    view:
        formats: { json: true, xml: false, rss: false }
        view_response_listener: true
    serializer:
        serialize_null: true
    format_listener:
        rules:
            - { path: '^/', priorities: ['json'], fallback_format: 'json' }

framework.yaml

sensio_framework_extra:
    view: { annotations: false }

You've disabled the SensioFrameworkExtra annotation for the view and this is wrong. You have to enable it. try this : view: { annotations: true } — Dayron Gallardo

Annotation system must be enabled indeed. Verify your annotation of view (maybe a typo ? You didnt paste the declaration). Last solution to me is to dump the result of this condition that does not act as expected in your case github.com/FriendsOfSymfony/FOSRestBundle/blob/… — Nek

I use FOSRest, but my controller looks like:

use FOS\RestBundle\Controller\FOSRestController;   //
use FOS\RestBundle\View\View;                       // <-- first import
use FOS\RestBundle\Controller\Annotations as Rest; //

class TagController extends FOSRestController      // <-- extend
{
    /**
     * Retrieves a collection of Tag resource.
     *
     * @Rest\View(serializerGroups={"details"})
     * @Rest\Get("/tag")                            // <-- rout
     */
    public function index(TagRepository $tagRepository): View // <-- use View
    {
        $data = $tagRepository->findAll();

        return View::create($data, Response::HTTP_OK);        // <-- how to return
    }
}
