Object hydration problem when the binding is null

[mcoutantL]

An error is raised if product insurer is empty, which obviously in view of the connection may be the case (left join). The error is No such field 'id'. Existing fields are {titre}

AutoStructure

class ProductAssureur extends RowStructure
{
    /**
     * __construct
     *
     * Structure definition.
     *
     * @access public
     */
    public function __construct()
    {
        $this
            ->setRelation('public.product_assureur')
            ->setPrimaryKey(['id'])
            ->addField('titre', 'varchar')
            ->addField('description', 'varchar')
            ->addField('is_active', 'bool')
            ->addField('id', 'int4')
            ->addField('created_at', 'timestamp')
            ->addField('updated_at', 'timestamp')
            ->addField('pdf_type', 'varchar')
            ->addField('path', 'varchar')
            ->addField('is_concurrent', 'bool')
            ;
    }
}

Query

$sql = <<<SQL
SELECT
    :projection
FROM
    :lead lead
    LEFT JOIN :lead_line lead_line_products ON lead_line_products.order_id = lead.id AND lead_line_products.type = 0
    LEFT JOIN lead_line lead_line_options ON lead_line_options.order_id = lead.id AND lead_line_options.type = 1
    LEFT JOIN :product_product ON lead_line_products.product_id = product_product.id
    LEFT JOIN product_product options ON options.id = lead_line_options.product_id
    LEFT JOIN :product_assureur ON product_product.assureur_id = product_assureur.id OR options.assureur_id = product_assureur.id
WHERE :condition
GROUP BY lead.id, product_assureur.*
ORDER BY $field $sorting
SQL;

$projection = $this->createProjection()->setField('product_assureur', 'product_assureur', '\Sel\Component\Model\****\PublicSchema\ProductAssureur');

Course results

foreach($results as $res) {
    var_dump($res);
}
exit;

When a $res is null (because does not have an product insurer)
