Demo is not working

[art-cg]

Hi. The Details pages of the demo are not working.
I am not sure if you are working on it right know.
Because first (3 min ago) i got a blank page and just a console error.
Now i get an Symfony Stacktrace.

http://symfony-react.limenius.com/recipe/1

Return value of Limenius\ReactRenderer\Twig\ReactRenderExtension::jsonDecode() must be of the type array, object returned

in src/Controller/RecipeController.php (line 45)
} return $this->render('recipe/recipe.html.twig', [
// A JSON string also works
'props' => $serializer->serialize( ['recipe' => $recipe ], 'json') ]); } /**
* @route("/redux/", name="homepage_redux")
