Autowire in Symfony in prefetchMethod is failing

[moufmouf]

I'm trying to autowire a service in a prefetchMethod in Symfony.

    /**
     * @Field(prefetchMethod="prefetchProducts")
     * @return Product[]
     */
    public function getProducts($sortedProducts)
    {
        return $sortedProducts[$this->getId()];
    }

    /**
     * @param Company[] $companies
     * @Autowire(for="$productRepository")
     * @return array<int, array<Product>>
     */
    public function prefetchProducts(iterable $companies, ProductRepository $productRepository)
    {
        $products = $productRepository->findByCompanies($companies);

        $sortedProducts = [];
        foreach ($products as $product) {
            $sortedProducts[$product->getId()][] = $product;
        }

        return $sortedProducts;
    }

I get this:

{
  "type": "https://tools.ietf.org/html/rfc2616#section-10",
  "title": "An error occurred",
  "status": 500,
  "detail": "The \"App\\Repository\\ProductRepository\" service or alias has been removed or inlined when the container was compiled. You should either make it public, or stop using the container directly and use dependency injection instead.",
  "class": "Symfony\\Component\\DependencyInjection\\Exception\\ServiceNotFoundException",
