I'm coding a telegram userbot (with telethon) which sends a message,every 60 seconds, to some chats.

I'm using 2 threads but I get the following errors: "*RuntimeWarning: coroutine 'sender' was never awaited*" and "*no running event loop*".

**My code**:

```
....

async def sender():
    for chat in chats :
        try:
            if  chat.megagroup == True:
                await client.send_message(chat, messaggio)
        except:
            await client.send_message(myID, 'error')
schedule.every(60).seconds.do(asyncio.create_task(sender()))

...
class checker1(Thread):
    def run(self):
        while True:
            schedule.run_pending()
            time.sleep(1)
class checker2(Thread):
    def run(self):
        while True:
            client.add_event_handler(handler)
            client.run_until_disconnected()
checker2().start()
checker1().start()

```

I searched for a solution but I didn't find anything...
