I followed the steps outlined in the README. However, I encountered the following error when I executed the Lambda:
Unable to import module 'handler': No module named 'selenium.webdriver.chrome'

If I try and run it as you have laid out I get the following error.
selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable may have wrong permissions. Please see https://sites.google.com/a/chromium.org/chromedriver/home

If I change
driver = webdriver.Chrome('/opt/chromedriver',chrome_options=options)
to
driver = webdriver.Chrome('/opt/chromedriver.exe',chrome_options=options) I get a new error

selenium.common.exceptions.WebDriverException: Message: 'chromedriver.exe' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

I know that the README has given specific versions to follow, but my existing scripts were written with Selenium 3.141.0 version. I was trying to use the same version here instead of 2.37, I ran into the error WebDriverException: Message: Service /opt/chromedriver unexpectedly exited. Status code was: 127.

Does anybody face the same issue?

In the deployment phase, i got a few warning logs like this:

Serverless: Configuration warning:
Serverless:   at 'layers.selenium': unrecognized property 'CompatibleRuntimes'
Serverless:   at 'layers.chromedriver': unrecognized property 'CompatibleRuntimes'
Serverless:  
Serverless: Learn more about configuration validation here: http://slss.io/configuration-validation

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)' ",

  ]
}

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?

Hi. Many thanks for sharing this. I'm struggling to change the S3 bucket from ServerlessDeploymentBucket. I've tried changing all references in lambda/.serverless/*.json files, but these are overwritten on sls deploy.

I've changed all references in the whole repo until search for ServerlessDeploymentBucket returns nothing, but they still come back! What am I missing?

hey guys,
I'm new to AWS Lambda just getting all running if I use the dashs ... how can I create all stuffs that is inside READ.ME ? do I have to open the cli Cludshell ? There is nothing like you are showing to get the ChromeDriver work ... sorry the dumb question ... but I need a light ...

I followed all steps in the README. When I execute the lambda function,

serverless invoke --function hello

I get the error:

{
    "errorMessage": "Message: 'ChromeDriver executable needs to be available in the path.                 Please download from http://code.google.com/p/chromedriver/downloads/list                and read up at http://code.google.com/p/selenium/wiki/ChromeDriver' ",
    "errorType": "WebDriverException",
    "stackTrace": [
        [
            "/var/task/handler.py",
            13,
            "hello",
            "driver = webdriver.Chrome('/opt/chromedriver', chrome_options=options)"
        ],
        [
            "/opt/python/lib/python3.6/site-packages/selenium/webdriver/chrome/webdriver.py",
            59,
            "__init__",
            "self.service.start()"
        ],
        [
            "/opt/python/lib/python3.6/site-packages/selenium/webdriver/chrome/service.py",
            68,
            "start",
            "and read up at http://code.google.com/p/selenium/wiki/ChromeDriver\")"
        ]
    ]
}

I have checked in the deployment bucket in S3 and the chromedriver file is under s3://selenium-layer-dev-serverlessdeploymentbucket-10lxthu8funhm/serverless/selenium-layer/dev/1586419384780-2020-04-09T08:03:04.780Z/chromedriver.zip, as it should be.

What are I missing?
