Seems like the user that the appservice is authenticated at isn't making it to the function somehow.

let sender_user = body.sender_user.as_ref().expect("user is authenticated");

is the user_id in the appservice's namespaces?

yep! the bots userid is @_ooye_bot:misty.cafe and the appservice has the following:

sender_localpart: _ooye_bot
namespaces:
  users:
    - exclusive: true
      regex: "@_ooye_.*:misty\\.cafe"
  aliases:
    - exclusive: true
      regex: "#_ooye_.*:misty\\.cafe"

it seems to panic only when I invite the bot and it attempts to join, if I use ooyes easy mode, which creates the new rooms by itself, there seems to be no issue and everything works as intended
