为什么我有消息'SQLSTATE [HY000]：一般错误'的未捕获异常'PDOException'？

I'm trying to do a inner join in a update, but it show an error message which is :

"Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]: General error'"

BUT the sql query works ! it updates correctly my field in my database...
So I don't know where the problem is...

Here are my tables : https://ibb.co/jZ7W3q7 and https://ibb.co/QnQMXx8

Here's my code :

// update ticket stock : 
foreach($test = $bdd->query('UPDATE ticket INNER JOIN chosen_ticket ON 
ticket.id_ticket = chosen_ticket.id_ticket SET ticket.stock = ticket.stock - 1 
WHERE chosen_ticket.id_reservation = "'. $_SESSION['idReservation'] .'"') as 
$updateTicket){
        }
