Do Subscribers work while loading Fixtures in Symfony? - symfony

Question

I tried to run the fixture below on Symfony 5 using the command php bin/console d:f:l.
I get this error: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'contact_email' cannot be null
The same code logic is working fine for Post entities when creating them manually through the CRUD. Are fixtures not compatible with subscribers (events) or did i make a mistake?
Thank you.
Edit: I'm also using EasyAdmin Bundle 3.

EasyCorp\Bundle\EasyAdminBundle\Event\BeforeEntityPersistedEvent:class is not proper Symfony event name. You probably should use Doctrine\ORM\Events::prePersist.
Also please check your DoctrineBundle version. If you're using the default services.yaml configuration and DoctrineBundle lower than 2.1, you have to configure services.yaml with:
App\EventListener\AuthorSubscriber:
tags:
- name: 'doctrine.event_subscriber'
