Hi Jan Philipp,
that's really weird, it's always working for us. Can you please verify you're sending the right parameters to the WebServices? Also, we always send the user id to mod_quiz_get_user_attempts, but it should still work without sending it...
Juan Leyva is the one who developed the WebServices but he isn't here this week, so you'll have to wait until next week to get a better response
Kind regards,
Dani
