Internal Server Error when trying to delete "big" files from pod

I get an internal server error when I try to delete "big" files from my pod at inrupt.net.
The files are a few megabytes big, you can find them here: https://harrystminrupt.inrupt.net/public/apps/website/
They are a relic from a react-app that I hosted there.

I have already tried different client-libraries and solid-apps for file-management of pods, but I always get the same error, which leads me to believe that this is a problem with the server (kind of obvious since it's an internal server error).

I also already created a post on the solidproject-forum, you can check it out for a bit more info:

Commencez par reproduire la suppression des fichiers liés de quelques mégaoctets depuis le pod inrupt.net, puis examinez les détails supplémentaires dans la publication liée du forum Solid Project. Comparez le comportement entre les bibliothèques clientes et les applications Solid mentionnées dans le rapport. Le travail est terminé lorsque ces fichiers peuvent être supprimés sans erreur interne du serveur.
