Cannot autowire service error

[seriousTom]

Hello, I tried to extend product repository like documented in sylius website I also tried to copy files from this repository, because I see the code differs a bit from the code in documentation. But in any case I get this error 'Cannot autowire service "App\Doctrine\ORM\ProductRepository": argument "$entityManager" of method "Sylius\Bundle\CoreBundle\Doctrine\ORM\ProductRepository::__construct()" references class "Doctrine\ORM\EntityManager" but no such service exists. Try changing the type-hint to one of its parents: interface "Doctrine\ORM\EntityManagerInterface", or interface "Doctrine\Common\Persistence\ObjectManager".'

Hi

I had this issue but on further inspection I just forgot to add the repository I created in the yaml file config/packages/_sylius.yaml.
https://docs.sylius.com/en/latest/customization/repository.html

2. In order to use your repository you need to configure it in the config/packages/_sylius.yaml. As you can see in the _sylius.yaml you already have a basic configuration, now you just need to add your repository and override resourceRepository
