EasyAdminBundle: EntityFilter not working with UUIDs

Describe the bug I have entities identified by uuids, the EntityFilter is not filtering them properly and returns no result.

To Reproduce I’ve recreated a blank project and I’m able to reproduce the bug following those steps :

symfony new ea_uuids --full
cd ea_uuids
composer require easycorp/easyadmin-bundle #latest version then

Then I’m creating two simple entities identified by uuids with custom generators UuidV4, following this symfony blog post.

symfony console make:entity Book
symfony console make:entity Category

Configuring EA :

symfony console make:admin:dashboard
symfony console make:admin:crud # create Book crud (With EntityFilter on category field) 
symfony console make:admin:crud # create Category crud

Then I’m creating a category via EA crud, and a book with this category associated.

    {

    public function addBook(Book $book): self
    {
        if (!$this->books->contains($book)) {
            $this->books[] = $book;
            $book->setCategory($this);
        }

        return $this;
    }

    public function removeBook(Book $book): self
    {
        if ($this->books->removeElement($book)) {
            // set the owning side to null (unless already changed)
            if ($book->getCategory() === $this) {
                $book->setCategory(null);
            }
        }

        return $this;
    }
}

src/Controller/Admin/BookCrudController.php

<?php

namespace App\Controller\Admin;

use App\Entity\Book;
use EasyCorp\Bundle\EasyAdminBundle\Config\Filters;
use EasyCorp\Bundle\EasyAdminBundle\Controller\AbstractCrudController;
use EasyCorp\Bundle\EasyAdminBundle\Field\AssociationField;
use EasyCorp\Bundle\EasyAdminBundle\Field\TextField;
use EasyCorp\Bundle\EasyAdminBundle\Filter\EntityFilter;

class BookCrudController extends AbstractCrudController
{
    public static function getEntityFqcn(): string
    {
        return Book::class;
    }

    public function configureFields(string $pageName): iterable
    {
        return [
            TextField::new('title'),
            AssociationField::new('category'),
        ];
    }

    public function configureFilters(Filters $filters): Filters
    {
        return $filters->add(EntityFilter::new('category'));
    }
}

I’m not adding other files (DasboardController / CategoryCrudController) since their configuration is trivial.

I’ve investigated EA code and found that if I add those modifications to vendor/easycorp/easyadmin-bundle/src/Filter/EntityFilter.php

- ->setParameter($parameterName, $value);
+ ->setParameter($parameterName, $value->getId(), 'uuid');

The filtering works fine, I have no idea how to fix this “properly” in a backward compatible way with classical auto-increment strategies.
