Good afternoon everyone. I’m using discord oauth2, after successful login the user appears. But after reloading the page it is deleted.

Logs:

Debug bar:
Before refresh:
user id is shown

After refresh:
N/A is shown

My User.php class:

#[ORMEntity(repositoryClass: BotRepositoryInterface::class)]

#[ORMHasLifecycleCallbacks]
class User implements UserInterface
{
    #[ORMId]
    #[ORMGeneratedValue]

    private ?int $id;

    #[ORMColumn(type: 'string', length: 255)]
    private ?string $username;

    #[ORMColumn(type: 'string', length: 250)]
    #[AssertConstraintsNotBlank]
    private ?string $description = "";

    #[ORMColumn(type: 'json')]

    public function __construct(?string $discordId)
    {
        $this->username = $discordId;
    }

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

    public function setId(?int $id): void
    {
        $this->id = $id;
    }

    public function getUsername(): ?string
    {
        return $this->username;
    }

    public function setUsername(?string $discordId): void
    {
        $this->username = $discordId;
    }

    public function getDescription(): ?string
    {
        return $this->description;
    }

    public function setDescription(?string $description): void
    {
        $this->description = $description;
    }


    public function getRoles(): array
    {
        $roles = $this->roles;
        $roles[] = 'ROLE_USER';
        return array_unique($roles);
    }

    public function eraseCredentials()
    {
        // TODO: Implement eraseCredentials() method.
    }

    public function getUserIdentifier(): string
    {
        return $this->username;
    }

    /** @see Serializable::serialize() */
    public function serialize(): string
    {
        return serialize(array(
            $this->id,
            $this->username,
            $this->description,
            $this->roles
        ));
    }

    /** @see Serializable::unserialize() */
    public function unserialize(string $serialized): void
    {
        list (
        $this->id,
        $this->username,
        $this->description,
        $this->roles
        ) = unserialize($serialized);
    }


}

What i need to do to fix this error?

I tried changing the User class by adding serialization
