Using Selenium Chromedriver in AWS Lambda using C#

I am looking to use Selenium Chromedriver in an AWS Lambda function using C# but I am not having much luck... My initial error that i was getting was that "chromedriver.exe does not exist in /tmp/". Using the Webdrivermanager got me past this error but now i am having issues with permissions "Access to the path '/tmp/' is denied."

I have google my fingers off and have tried multiple ways of getting this to work. I bet it is something small that i am missing.

Any help would be greatly appreciated.

using System.Collections.Generic;
using Amazon.Lambda.Core;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using WebDriverManager; 

public class Function
{
    public void FunctionHandler(string input, ILambdaContext context)
    {
        var driver = GetDriver();
        driver.Navigate().GoToUrl(input);
        driver.Quit();
    }

    public IWebDriver GetDriver()
    {
        new DriverManager().SetUpDriver(
            "http://chromedriver.storage.googleapis.com/75.0.3770.8/chromedriver_win32.zip", 
            "/tmp/", 
            "chromedriver.exe"
        );

        ChromeOptions options = new ChromeOptions();
        options.AddArguments(new List<string>() {
            "--no-sandbox",
            "--headless",
            "--disable-gpu",
            "--homedir=/tmp"
        });
        return new ChromeDriver("/tmp/", options);
    }
}

Looking into AWS Lambda Runtimes page

Operating system – Amazon Linux

AMI – amzn-ami-hvm-2017.03.1.20170812-x86_64-gp2

Linux kernel – 4.14.77-70.59.amzn1.x86_64

So I believe you should be using the Linux Chromedriver, to wit replace this line:

http://chromedriver.storage.googleapis.com/75.0.3770.8/chromedriver_win32.zip

with this one:

https://chromedriver.storage.googleapis.com/75.0.3770.8/chromedriver_linux64.zip

and maybe chromedriver.exe with just chromedriver

If you're going to invest into cloud-based web browser automation it might be easier to go for a specialized service like Saucelabs or Experitest
