Nullable parameters in PHP generated classes

[ezimuel]

Some generated the Schema classes have the nullable option (?) in constructor but they don't have nullable in the property definition. For instance, the ExtractUrlIndexingResults in AppSearch\Schema :

namespace Elastic\EnterpriseSearch\AppSearch\Schema;

/**
 * @generated This file is generated, please do not edit
 */
class ExtractUrlIndexingResults
{
	public string $document_id;
	public object $document_fields;


	public function __construct(?string $document_id, ?object $document_fields)
	{
		$this->document_id = $document_id;
		$this->document_fields = $document_fields;
	}
}

In this example, the $document_id and the $document_fields properties will generate a FATAL error when set to null.
The FATAL error at runtime will be PHP Fatal error: Uncaught TypeError: Cannot assign null to property.
We need to fix this adding nullable also in the definition, as follows:

namespace Elastic\EnterpriseSearch\AppSearch\Schema;

/**
 * @generated This file is generated, please do not edit
 */
class ExtractUrlIndexingResults
{
	public ?string $document_id;
	public ?object $document_fields;


	public function __construct(?string $document_id, ?object $document_fields)
	{
		$this->document_id = $document_id;
		$this->document_fields = $document_fields;
	}
}
