What should I do when I receive an error saying 'coroutine was never awaited' with asyncio.create_task?

I want to create a task with asyncio.create_task, which must run in the background without blocking currently running function. However, when I attempt to create it, I get an error, saying that coroutine was never awaited.

I tried to just call create_task() with a coroutine without awaiting it first, thinking that it would run after I created the task:

async def _turn_end_timer(self):
    await asyncio.sleep(self.turn_time)
    self.next_turn()
def next_turn(self):
    if self._turn_worker is not None:
        self._turn_worker.cancel()
    if len(self.turn_queue) == 0:
        self.current_turn_username = None
        return
    self.current_turn_username = self.turn_queue.pop(0)
    coro = self._turn_end_timer()
    self._turn_worker = asyncio.create_task(coro)
    self.send_turn_queue_update()

That did not work. The event loop is running:

asyncio.get_event_loop().run_until_complete(main())
asyncio.get_event_loop().run_forever()

What does that mean and how to fix it? I do not want to use threading module, since it would cause more trouble.

asyncio would not allow multiple event_loop to run but if you need a by pass that is you are getting the event_loop already running then you can use this library

import nest_asyncio
nest_asyncio.apply()

This will allow for a multi threaded behaviour
