after trying to add a new sub category to my Discourse instance, I’ve noticed the following error:
My intention was, to make this category only available for admins. Instead of “admins”, a user group called “undefined” was added and I’ve got this error message. In case of making this category available for everyone, everything works fines.
Any clue why this error message occurs?
