AttributeError: 'coroutine' object has no attribute 'edit'

I am making a discord bot:

There is an async function that corresponds to a slash command. I have another function called count():

async def count(n):
    for i in range(n):
        yield i

and in the slash command function:

msg = ctx.respond("")
for i in count(n):
    await msg.edit(i)

I got the following error:
discord.errors.ApplicationCommandInvokeError: Application Command raised an exception: TypeError: 'async_generator' object is not iterable

So I looked up some suggestions on Stack Overflow and changed my code to:

global msg
msg = ctx.respond("")

async def counnnt(n):
    async for i in count(n):
        await msg.edit(i)

asyncio.run(counnnt(n))

Finally I got this error:
discord.errors.ApplicationCommandInvokeError: Application Command raised an exception: AttributeError: 'coroutine' object has no attribute 'edit'

(obviously I am not doing count() in my bot but something very similar)
I appreciate any suggestions 🙂
