RuntimeError: Timeout context manager should be used inside a task

So, basically I want to use starlette (https://www.starlette.io/) as a webhook for telegram bot and iogram as a way to handle bot messages.

I’ve created an endpoint to get the telegram bot updates:

class UpdateTelegramBotEndpoint(HTTPEndpoint):
    async def post(self, request):
        update_data = await request.json()
        await process_update(update_data)
        return JSONResponse(update_data, status_code=200)

The process_update function (I actually don’t know whether it is right to use .set_current() methods, but that’s is not a point):

async def process_update(update_data: dict):
    update = Update(**update_data)

    Bot.set_current(bot)
    Dispatcher.set_current(dispatcher)

    return await dispatcher.process_update(update)

Message handler function:

bot = Bot(token=settings.TELEGRAM_API_KEY)
dispatcher = Dispatcher(bot)


@dispatcher.message_handler(commands=('start', 'help'))
async def send_help_message(message):
    await message.reply(
        '*NoteBot welcomes you!*\n\n'
        'Forward me a message from a channel to save it as Evernote note. '
        'Admit that you should grant access for me to be able to create'
        'notes for you.\n\n'
        '*Commands*:\n'
        '\t/login - Login into Evernote',
        parse_mode='Markdown'
    )

When I’m trying to send bot a /help message, I’m getting such error:

INFO:     91.108.6.40:0 - "POST /updates/ HTTP/1.1" 500 Internal Server Error

RuntimeError: Timeout context manager should be used inside a task

Is there any way I can fix this? The thing I want to do is to get update from telegram api -> process it asynchronious with aiogram’s bot -> send user a message.

Is there any way I can deal with it or should I use starlette and telegram bot separately (that is not prefered, as I have some other endpoints to same telegram user/chat data into my mongoDB).

Yeah, that’s what I thought about. You’re using uvloop (uvicorn’s dependency). It’s known (but not yet properly reported) bug with aiohttp, uvloop and Python 3.7+

ref: MagicStack/uvloop#274

[evgfilim1]

As far as I know, aiohttp works perfectly with uvloop

@uwinx it does work, but not with timers (at least in aiogram, IDK why) By saying “it doesn’t work” I mean timers (see traceback, @vitaliy-diachkov is not the only one who faces this, at least me too)

let us know here if we can close it?

Don’t close it as it is still a bug in aiogram
