Doctrine overwrite column value for composite key - doctrine

Question

I need a relation uniderect one-to-one through composite key. I am using PostgreSQL.
#[Entity()]
#[Table(name: "passengers")]
class Passenger
{
#[Id]
#[Column(type: "uuid")]
private string $id;
#[Id]
#[Column(type: "uuid")]
private string $projectId;
#[OneToOne(targetEntity: "Ticket", cascade: ["persist"])]
#[JoinColumn(name: "ticket_id", referencedColumnName: "id")]
#[JoinColumn(name: "project_id", referencedColumnName: "project_id")]
private ?Ticket $ticket;
/**
* #return string
*/
public function getId(): string
{
return $this->id;
}
/**
* #param string $id
*/
public function setId(string $id): void
{
$this->id = $id;
}
/**
* #return string
*/
public function getProjectId(): string
{
return $this->projectId;
}
/**
* #param string $projectId
*/
public function setProjectId(string $projectId): void
{
$this->projectId = $projectId;
}
/**
* #return Ticket|null
*/
public function getTicket(): ?Ticket
{
return $this->ticket;
}
/**
* #param Ticket|null $ticket
*/
public function setTicket(?Ticket $ticket): void
{
$this->ticket = $ticket;
}
}
#[Entity()]
#[Table(name: "tickets")]
class Ticket
{
#[Id]
#[Column(type: Types::STRING)]
private string $id;
#[Id]
#[Column(type: "uuid")]
private string $projectId;
/**
* #return string
*/
public function getId(): string
{
return $this->id;
}
/**
* #param string $id
*/
public function setId(string $id): void
{
$this->id = $id;
}
/**
* #return string
*/
public function getProjectId(): string
{
return $this->projectId;
}
/**
* #param string $projectId
*/
public function setProjectId(string $projectId): void
{
$this->projectId = $projectId;
}
}
I'm trying to persist Passenger entity without Ticket entity:
$passenger = new Passenger();
$passenger->setId('07f5f7c8-def7-4fad-a146-b573421d8832');
$passenger->setProjectId('48ae51a1-4405-4f1d-8061-55a732d383a1');
$this->entityManager->persist($passenger);
$this->entityManager->flush();
I get an error:
Doctrine\DBAL\Exception\NotNullConstraintViolationException : An exception occurred while executing 'INSERT INTO passengers (id, project_id, ticket_id) VALUES (?, ?, ?)' with params ["07f5f7c8-def7-4fad-a146-b573421d8832", null, null]:
SQLSTATE[23502]: Not null violation: 7 ERROR: null value in column "project_id" of relation "passengers" violates not-null constraint
DETAIL: Failing row contains (07f5f7c8-def7-4fad-a146-b573421d8832, null, null).
I want to draw your attention to the fact that doctrine in sql overwrite the value of project_id for composite key to null.
If I persist Passenger by specifying the Ticket, everything works without errors.
Is this a doctrine bug or am I doing something wrong?
