symfony – How to use Doctrine Extensions on the Api platform

I'm using stofDoctrineExtensionsBundle in a Symfony 4 project with Api Platform. I have immovable Y time stamp Active extensions. It works like a spell when I persist the entities manually, that is, in the accessories, but when I persist through the operations of collection of publications, it does not do it and says that those fields (slug, createdAt and updatedAt) are obligatory.
I can not find a solution for this after several days.
Thank you very much (this is my first question here).
