Great, Thanks!

Just out of curiosity, how this will be released as a new package?

from pyppeteer.

i'm running into this also

from pyppeteer.

cnicodeme avatar cnicodeme commented on May 15, 2024

Yes, I confirm this too.

On my side, this occurs when I call

    browser.close()
    try:
        loop.run_until_complete(asyncio.gather(*asyncio.Task.all_tasks()))
    except Exception as e:
        # The above mentionned exception is caught here
        pass

from pyppeteer.

I still encounter this in 0.0.14! T_T

from pyppeteer.

Though a bit different:

future: <Task finished coro=<Connection._async_send() done, defined at /usr/local/lib/python3.6/site-packages/pyppeteer/connection.py:61> exception=ConnectionClosed('WebSocket connection is closed: code = 1006 (connection closed abnormally [internal]), no reason',)>
Traceback (most recent call last):

    yield from self.ensure_open()

    raise ConnectionClosed(self.close_code, self.close_reason)

from pyppeteer.

Thank! And thank you for your work on this library - it's very good mostly.
Updated, still the same issue.

Task exception was never retrieved

websockets.exceptions.ConnectionClosed: WebSocket connection is closed: code = 1006 (connection closed abnormally [internal]), no reason

And the most sad thing is I don't see how do I intercept and handle this error, do you know how?
Because it freezes the whole python process. BTW noticed that child chrome process at this point becomes a zombie-process.

Could you show the sample code to reproduce this error?

from pyppeteer.

scythargon avatar scythargon commented on May 15, 2024

I'll try to prepare one later, because it requires quite a few libraries to be incorporated together
