Screenshot fails with timeout error when running in lambdas for some sites

[anejaalekh]

How to reproduce:
Deploy a lambda function with chrome to take the screenshot, try to take the screenshot for https://github.com. You should see the below error in the lambda function logs.

Error in Lambda:
[ERROR] NetworkError: Protocol error Page.captureScreenshot: Target closed.
Traceback (most recent call last):
  File "/var/task/k8_live_servers/lambdas/screenshot.py", line 14, in run
    js_code   = js_code)

    screenshot_file = await self.screenshot(url=url,page=page, full_page=full_page, clip=clip, delay=delay, js_code=js_code)
  File "/var/task/osbot_browser/browser/API_Browser.py", line 231, in screenshot
    await page.screenshot({'path': file_screenshot,'fullPage': full_page, 'clip' : clip})
  File "/tmp/lambdas-dependencies/pyppeteer2/pyppeteer/page.py", line 1255, in screenshot
    return await self._screenshotTask(screenshotType, options)
  File "/tmp/lambdas-dependencies/pyppeteer2/pyppeteer/page.py", line 1302, in _screenshotTask
    result = await self._client.send('Page.captureScreenshot', opt)

To fix that, AWS SAM https://aws.amazon.com/serverless/sam/ can be used to simulate the error locally. Docker image for lambda can be created and that can be used for testing locally.
