I do have a strange behaviour i was not able to see in other tickets. The shopware 5 setup is based on composer, so the extension is also installed via composer and the PHP-Version used is PHP 8.
When trying to process the payment in the cart page, the server will throw a HTTP 500. This is the log i get.

Based on the error i assume that the Plugin-Handler should check for a specific object, but as it is NULL, PHP 8 will throw an exception. I have no clue, if this might be a mollie error, as i do not have the same behaviour with the integrated Pay Pal payment.
vendor/shopware/shopware/engine/Library/Enlight/Event/Handler/Plugin.php(148): method_exists(NULL, 'onOrder')
