Hi, could you please share more context? at least the stack trace would be helpful

Do you mean this?

Careful, database "api_presupuesto_db/" will be purged. Do you want to continue? (yes/no) [no]:

yes

This same procedure used to work a month ago, but now it doesn't...

By the way if I modify Vendor > zenstruck > foundry > src> Factory.php and initialize the $class attribute to the exact name of the Entity I want to create, it works...

Any help will be appreciated.

I can't understand how this could be possible.

could you share BudgetFixtures as well as your factory's code please?

BudgetFixtures.php:

    use Doctrine\Bundle\FixturesBundle\Fixture;

        use App\Factory\BudgetFactory;

        class BudgetFixtures extends Fixture
        {
            public function load(ObjectManager $manager): void
            {

                BudgetFactory::createMany(5);
              //  $manager->flush();
            }
        }

Thank you, again.
