Core: [2.4-beta.2] DataProvider with subResource: the uri leads to a 500 because The manager for my Entity must be an EntityManager

[Rebolon]

Hi,

i have a simple entity that define an endpoint and that is not a Doctrine Entity. It declares some properties and one of them is a subResource. This mapping of this subResource is a class that has both Doctrine nd ApiPlatform annotation (it's a light classe and it seems a quicker solution without impact).
If i call the sub resource, then i have a 500 which is logic because:
in api-platform\core\src\Bridge\Doctrine\Orm\SubresourceDataProvider.php::line 139 it does a $this->managerRegistry->getManagerForClass(EntityClass) where the EntityClass is the Api definition, not the Doctrine Entity, so no Manager is available.

How should we deal with this of error ?

Here is the stack:

Because your resource is not a doctrine-managed entity you should do a data provider for it.
