unknown error: unable to discover open pages

[Denijar]

I keep encountering this error message when I try and run in AWS Lambda:

{
  "errorMessage": "Message: 'unknown error: unable to discover open pages\\n  (Driver info: chromedriver=2.37.544315 (730aa6a5fdba159ac9f4c1e8cbc59bf1b5ce12b7),platform=Linux 4.14.165-102.205.amzn2.x86_64 x86_64)' ",
  "errorType": "WebDriverException",
  "stackTrace": [

      "lambda_handler",

    ],
    [

    ],
    [

      "execute",
      "self.error_handler.check_response(response)"
    ],
    [
      "/var/task/lib/selenium/webdriver/remote/errorhandler.py",
      164,

    ]
  ]
}

I encounter this when using the version stack you have suggested: Python3.6, Selenium2.37, ChromeDriver2.37, Serverless Chrome v1.0.0-41.

I also encounter it when I use the version stack that has been discussed in this issue as being a compatible set of versions (Python3.6, Selenium3.14, ChromeDriver2.43, Serverless Chrome v1.0.0-55).

Some Googling has suggested that adding chrome_options.add_argument('--no-sandbox') is a fix but this has not worked for me.

Any suggestions?

I have the same issue. The browser is an empty page suggesting some sort of compatibility issue, but it has no problem finding the title?

Same from here. It takes forever and there is no response.

Did anyone able to solve this issue?
