For all repeatable attributes I get the following error in Psalm 6.14.1 and PHP 8.5 (when they are repeated):
ERROR: InvalidAttribute - src/App/Controller/CustomerController.php:41:7 - Attribute Route is not repeatable (see https://psalm.dev/242)
#[Route('/customer/create', methods: ['GET', 'POST'], name: 'customer_create')]
In PHP 8.4 this error does not occur, so something about PHP 8.5 seems to throw Psalm off.
