Printer app not working

hi,

i was trying to enable Printer app on my newly system and have cups and cups-bsd installed. I can print a testpage from cups admin pages and my printer is set up as standard printer and www-data is allowed to print there. However, if i try to print i get a spinning wheel in the printer tab and i see this error message in nextcloud log:

Exception: Call to a member function getLocalFile() on null in file '/var/www/nextcloud/lib/private/Files/Filesystem.php' line 529
