The async def prev(self, count=None) and async def next(self, count=None) methods on client/viscera/events.py are not using await when calling self._fetch, which is causing errors when the async iterator tries to continue reading events of a previous/next page.
How to reproduce:
events = await client.events.query()
async for e in events.forwards():
print(e.event_id, e.event_type)The snippet above will fetch some events and then throw an error:

To fix, we just need to add await to the following lines:
