bot.download_file causes Aiohttp ClientError: ClientOSError

[yudytskiy]

Hi. Here is small bot demonstrates the problem:

import asyncio
from telebot.async_telebot import AsyncTeleBot

TOKEN = '**********'
bot = AsyncTeleBot(TOKEN)

@bot.message_handler(commands=['id'])
async def id_command(message):
    return await bot.reply_to(message, text=f'Your id: {message.chat.id}')

@bot.message_handler(content_types=['photo'])
async def photo_handler(message):
    file_id = message.photo[-1].file_id
    file_info = await bot.get_file(file_id)
    # This download method causes:
    # Aiohttp ClientError: ClientOSError and then
    # Request timeout. Request: .... and then
    # Infinity polling: polling exited
    # on the next message 
    _file = await bot.download_file(file_info.file_path)
    return await bot.reply_to(message, f'Path: {file_info.file_path}; Length:{len(_file)}' )

if __name__ == '__main__':
    loop = asyncio.new_event_loop()
    # Not recovering with infinity_polling: await self._process_polling(non_stop=False....
    # Version 4.6.0 recovering after Aiohttp ClientError
    # Version 4.6.1 and 4.7.0 not recovering
    loop.create_task(bot.infinity_polling())
    # Recovering:
    # loop.create_task(bot.polling(non_stop=True))
    loop.run_forever()

# The scenario:
# - bot is run
# - send /id command and get reply
# - send any image file and get the filename and file length
# - send /id and get polling exited with:
# (asyncio_helper.py:80 MainThread) ERROR - TeleBot: "Aiohttp ClientError: ClientOSError"
# (async_telebot.py:317 MainThread) ERROR - TeleBot: "Request timeout. Request: method=get url=getUpdates params=<aiohttp.formdata.FormData object at 0x0000025A91E391E0> files=None request_timeout=None"
# (async_telebot.py:276 MainThread) ERROR - TeleBot: "Infinity polling: polling exited"
# (async_telebot.py:278 MainThread) ERROR - TeleBot: "Break infinity polling"

Your os? You were supposed to answer to this questions. I think this might happen due to file rights

pass non_stop=True to continue the work of the polling

Btw, you should create an issue on official repo, not here
