Hey FOSDEM folks, I just tried buying an XL male shirt from https://treasure.fosdem.org. While scanning the Bancontact code, I could perfectly accept payment in the KBC app, but then got redirected to an error 500 page (see screenshot). On my banking app, I saw a 25 euro reservation, which has converted to a full payment while writing this email (see payment export PDF, for some reason with a one hour off timestamp). I've however not received any confirmation email. I'm therefore not really sure if things went through correctly or not. I really want to be sure I get a shirt (as I've gotten one every year), so I wanted to reserve one to be sure. Thank you in advance for your help! Kind regards, Bert Van de Poel PS: I speak Dutch, so if you do as well, feel free to answer me in English or Dutch.
