async def create_bot(client : TelegramClient, username):

    msg = await conservation.send_message('/newbot')
    response = await conservation.get_response()

Expected behavior

why no answer :(

[Lonami]

I have no intention to maintain conversation myself (which is why v2 removes it).

[Sonys9]

i gotchu i will try to recode it myself because conservation is nice

[Lonami]

Thanks, and feel free to send a pull request if you find a fix.

i see due is None, checking why...

[Sonys9]

I got it

at start, self._total_due = None

in function aenter if self._total_timeout: self._total_due = time.time() + self._total_timeout else: self._total_due = float('inf') but this function isnt calling

[Sonys9]

for some reason, after fixing, its gives TimeoutError, need to check why

[Sonys9]

its hard for me, so, i cant fix it :( (and im lazy)

but what i found:

1. due in _get_result may be None, so, i changed some code to

if timeout is None:
            timeout = self._timeout

        if timeout:
            due = time.time() + timeout
        else:
            due = float('inf')

        if timeout is not None:
            print(due, start_time, timeout)
            due = min(due, start_time + timeout)

2. I think, its not reading new messages, because incoming list is empty.
