error getting powerlevels if bot has powerlevel 0

[ryanlerch]

When trying to start a meeting in a room where the powerlevel of the bot is 0, for the self.client.state_store.get_power_levels(evt.room_id) call results in None -- for some reason, a user with powerlevel 0 cannot see the powerlevels?

Traceback (most recent call last):

I can't replicate this @ryanlerch, I'm afraid. My powerlevel-0 bot can check my powerlevel and deny me access if required:

# Confirm powerlevel
Gwmngilfen changed the power level of ER Maubot from Default to Custom (1).
Gwmngilfen changed the power level of ER Maubot from Custom (1) to Default.
# config min level to 50
Gwmngilfen> !sm
ER Maubot> Meeting started at 2023-09-08 09:24:07 UTC
The Meeting name is 'Meeting Test Meeting started 2023-09-08 09:24:07'
# wipe db and config min level to 150
Gwmngilfen> !sm
ER Maubot> You do not have permission to start a meeting

Is there anything special about your rooms? I've noticed my own powerlevel getting set to 1 instead of 0 in some Fedora rooms....
