ApiPlatform makes default serializer service broken

[karrakoliko]

API Platform version(s) affected: 3.1.16

Description
I want use Serializer service to serialize Api-Platform connected entity (e.g. entity has #[ApiResource] attribute) before it is persisted.

I create serialization group productSnapshot, assign it to the needed fields/getters in my entity.

public function __construct(protected SerializerInterface $serializer)...

public function someMethod(){
// <...>
    $this->serializer->serialize($product, 'json', ['groups' => 'productSnapshot']);
}

I get Unable to generate an IRI for the item of type "App\Entity\***.
I don't even care about IRI or api-platform features in this case: i just want to be able to use Symfony Serializer on it's own.

How to reproduce

• Entity should have #[ApiResource] attribute
• Fill some fields to entity, but don't persist
• Try serialize it

Possible Solution

Workaround 1

I can provide dummy iri as context:

$this->serializer->serialize($product, 'json', ['groups' => 'productSnapshot','iri'=>'take-this-iri-and-stop-throwing-exception']);

Workaround 2

I can configure custom serializer service, and use it instead of default serializer.

Workaround 3

I'm not sure about this one, but i think it is possible to:

1. override AbstractItemNormalizer/ItemNormalizer to have a context like do-not-use-api-platform-normalizers-for-gods-sake
2. make default symfony serializer skip api-platform normalizers in chain if that context met

All workarounds seems hacky, because, i think, api-platform serializers/normalizers should not interfere with default symfony serializer work.

In my opinion, these there must be:
a) a way to have ability to exclude api-platform normalizers/serializers from default serializer (blacklist mode)
b) api-platform normalizers/serializers should not be loaded in default serializer chain at all (whitelist mode)
c) whitelist/blacklist behaviour should be configurable

It's a problem for a long time #2579. We should probably redeclare our normalizer with an api platform specific tag though? In the meantime you can probably inject the ObjectNormalizer directly or make it work as the iri should be serializable, do you have a stack trace?
