@loiclau can you explain the idea behind the changes?

[victorvassilev]

please explain what is the reason for this change, we can't understand it

[loiclau]

It's because the webservice need a repository to work.
It's add and initialized on the service provider.
Without this change we can not create objects with argument.

You can register your webservice here

			->getRepository(Repository\MyRepository::class)
			->someMethodFromRepository();
