CancelledError when running on apify infrastructure

[krasnoludkolo]

Hello.
I'm running my actors on apify infrastructure and low % of runs ends with:

  Traceback (most recent call last):
  File "/usr/local/lib/python3.11/site-packages/websockets/legacy/protocol.py", line 1289, in close_connection
    await self.transfer_data_task
  File "/usr/local/lib/python3.11/site-packages/websockets/legacy/protocol.py", line 966, in transfer_data
    await asyncio.shield(self._put_message_waiter)
asyncio.exceptions.CancelledError

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/usr/local/lib/python3.11/site-packages/apify/event_manager.py", line 222, in _process_platform_messages
    async for message in websocket:

    yield await self.recv()
          ^^^^^^^^^^^^^^^^^

    await self.ensure_open()
  File "/usr/local/lib/python3.11/site-packages/websockets/legacy/protocol.py", line 940, in ensure_open
    raise self.connection_closed_exc()
websockets.exceptions.ConnectionClosedError: sent 1011 (internal error) keepalive ping timeout; no close frame received

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    async with Actor:

    return await cls._get_default_instance().exit(
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    self._connected_to_platform_websocket.set_result(False)
asyncio.exceptions.InvalidStateError: invalid state

Is there anything I can do about it?

Hey @krasnoludkolo, we will need more information to reproduce the problem and help you.

1. Could you provide us versions of the software you are using (Apify SDK, websockets, ...) - you can use pip freeze.
2. Could you provide us a minimal reproducible example? Share a small snippet of the code you are using, or describe the specific steps that lead to this issue. So that we are able to reproduce the error.
3. Since it seems websockets-related, I believe it is happening only when running on the Apify Platform, right? You have no issues running it locally, correct?
4. Could you provide more detailed logs from Apify's platform? Or any other relevant information?
