[SEVERE] The communication with Chromium are disconnected after 20 seconds.

[PCXDME]

The connection/communication with Chromium are disconnected after 20 seconds.
So if you do something after 20 seconds, app will crash.

This will fail.

import asyncio
from pyppeteer import launch

async def main():
    browser = await launch()
    page = await browser.newPage()
    await page.goto('http://example.com')
    await asyncio.sleep(20)
    await page.screenshot({'path': 'example.png'})
    await browser.close()

asyncio.get_event_loop().run_until_complete(main())

Solution:
https://github.com/miyakogi/pyppeteer/blob/master/pyppeteer/connection.py#L43
The websockets.client.connect should be called with these parameters.
ping_interval=None
ping_timeout=None

This is fixed in https://github.com/pyppeteer/pyppeteer2

Hi,

Is this going to be addressed in future releases?
