Selenium in "HeadLess" mode "Runtime.executionContextCreated has invalid 'context'" on Vagrant [duplicate] - python-3.x

Question

I'm trying to get started using selenium and have downloaded a chrome driver and put into my classpath. I'm just trying to get the title right now to see if I can get it to work. Code currently looks like this:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class Flows {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "/Users/mn/Desktop/project/turv/src/main/chromedriver");
WebDriver driver = new ChromeDriver();
String baseUrl = "http://google.dk/";
driver.get(baseUrl);
System.out.println(driver.getTitle());
driver.close();
}
}
I expected my output to be something along the lines of "Google", but I get this error instead:

I cant really figure out what the error is trying to tell me. Is it because I'm asking for the title before it has fully loaded the site maybe? Do I need to add some kind of waitforit command before the getTitle() ?

This error message...
org.openqa.selenium.WebDriverException: unknown error: Runtime.executionContextCreated has invalid 'context': {"auxData":{"frameId":"11895A1B77AC560388AA2919259E1422","isDefault":true},"id":1,"name":"","origin":"://"}
...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Your main issue is the version compatibility between the binaries you are using as follows :
You are using chromedriver=2.8 which is pretty ancient.
You are using chrome=66.0
Release Notes of ChromeDriver v2.38 clearly mentions the following :
Supports Chrome v65-67
So there is a clear mismatch between ChromeDriver version (v2.8) and the Chrome Browser version (v66.0)
Solution
Upgrade ChromeDriver to current ChromeDriver v2.38 level.
Keep Chrome version at Chrome v66.x levels. (as per ChromeDriver v2.38 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your #Test.
Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
