Summary

After upgraded to the latest version, we are having trouble hydrating entities containing an enum, after a DQL query

Current behavior

App\Entity\Enum\ArticleState::from(): Argument #1 ($value) must be of type string, App\Entity\Enum\ArticleState given

How to reproduce

1. Create the entity

class Article
{
    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column]
    private ?int $id = null;

    #[ORM\Column(length: 255, enumType: ArticleState::class)]
    private ?ArticleState $state = null;

    public function getId(): ?int
    {
        return $this->id;
    }

    public function setName(string $name): self
    {
        $this->name = $name;

        return $this;
    }

    public function getState(): ?ArticleState
    {
        return $this->state;
    }

    public function setState(ArticleState $state): self
    {
        $this->state = $state;

        return $this;
    }
}

2. Create the enum

enum ArticleState: string
{
    case ONLINE = 'online';
    case OFFLINE = 'offline';
}

3. Add the repository request

    /**
     * @return Article[]
     */
    public function findByState(ArticleState $articleState): array
    {
        return $this->createQueryBuilder('a')
            ->andWhere('a.state = :state')
            ->setParameter('state', $articleState->value)
            ->getQuery()
            ->getResult();
    }

4. Try the request, and you will get this error :

App\Entity\Enum\ArticleState::from(): Argument #1 ($value) must be of type string, App\Entity\Enum\ArticleState given
