When I fetch the same users as the initial channels

UAT = "some token"
user = "user"
class Bot(commands.Bot):
    def __init__(self):
        super().__init__(
            token=UAT,
            prefix="!",
            initial_channels=[user]
        )
    async def __ainit__(self):
        users = await self.fetch_users([user])
bot = Bot()
bot.loop.run_until_complete(bot.__ainit__())
bot.run()

I will add that I and other people on my project experience the exact same issue on our project, for the same reason.

Which version did you start getting this error on? If it's master after which commit did you last install?

[preeded]

It was 2.4.0 and I just got the same error from master.

Okay... I changed some code.

UAT = "some token"
user = "user"
class Bot(commands.Bot):
    def __init__(self):
        super().__init__(
            token=UAT,
            prefix="!",
            initial_channels=[user]
        )
    async def event_ready(self):
        self.loop.create_task(self.__ainit__())
    async def __ainit__(self):
        users = await self.fetch_users([user])
bot = Bot()
bot.run()

And I don't know why it looks like working... Doc says run():

A blocking function that starts the asyncio event loop, connects to the twitch IRC server, and cleans up when done.

I understood that bot.run() only connects to the event loop and the Twitch IRC server, so I thought my code would be okay because my code runs the event loop separately and fetch_users requests to the Twitch API server, not the Twitch IRC server. Is there something wrong with my understanding? Why doesn't it work if the same users are in the list of initial_channels? commands.Bot __init__ do something more? Like affecting to fetch_users API request?

We've (read: @chillymosh ) been attempting to trace this issue, and so far we've determined that using loop.run_until_complete before bot.run causes nick to get set to None, thus causing this error.

Is there something wrong with my understanding?

nope, thats how its supposed to work in theory.

Why doesn't it work if the same users are in the list of initial_channels?

it actually doesnt have anything to do with that, as mentioned above, it seems to be usage of run_until_complete.

This is entirely a bug, we'll have it fixed for the next release (hopefully)

@preeded I believe I have resolved this in f111e676cbd2988ca8d99ba84b0b8be118354ae1 which you can test by installing TwitchIO direct from master

[preeded]

Thank you very much for your help! I just tested it on the master, and it worked well!
