Sometimes I see this error in chrome (phantomjs works fine).

I have found a possible solution: http://stackoverflow.com/questions/27497875/selenium-grid-running-tests-in-parallel

Do not set driver in the base class, do not have driver property at all. The same instance is being overridden by different threadlocal drivers.
Any time you want to run your test, refer to WebDriverSetup.getDriver() in your test method itself and in your after/before methods.

PS: My tests are starting via Launcher, if it can help

If you delete the session we set the sessionID to null. As you can see in the logs you execute: 17:35:03.468 INFO - Executing: [find elements: By.id: b-letters]) after the test is done. Looks like a race condition in your test.

There's no any warnings and #b-letters exists
How to keep the session?

I can replicate it only with Chrome browser. And have no idea who may throw that exception

the wdio test runner because

So, how to know the reason? I could not find any information in the logs

If the spec has finished the wdio runner automatically shuts down the session

My test case (nothing else):

browser.url(url);
browser.setCookie(cookie);
browser.url(url); 
browser.waitForExist(selector);

Cannot understand how it's possible within one test case

I can't not tell you anything more without having a reproducible example or something I can investigate on.

I can reproduce it on Windows with Cygwin in Chrome.
PS: Works fine on Mac.

I'm having the same error as session ID is null. I have created a selenium grid with firefox and chrome. Below is my code:

Yaml file

version: "3"
services:
selenium-hub:
image: selenium/hub:latest
container_name: selenium-hub
ports:
- "4444:4444"
chrome:
image: selenium/node-chrome-debug:latest
volumes:
- /dev/shm:/dev/shm
depends_on:
- selenium-hub
environment:
- HUB_HOST=selenium-hub
- HUB_PORT=4444
firefox:
image: selenium/node-firefox:latest
volumes:
- /dev/shm:/dev/shm
depends_on:
- selenium-hub
environment:
- HUB_HOST=selenium-hub
- HUB_PORT=4444

Test case file

package docker

import java.net.{MalformedURLException, URL}

import org.openqa.selenium.remote.{DesiredCapabilities, RemoteWebDriver}
import org.openqa.selenium.{OutputType, TakesScreenshot, WebDriver}
import org.scalatest.{BeforeAndAfter, FlatSpecLike, Matchers}
import org.testng.annotations._
import org.testng.annotations.Test

class SignUpTests_Chrome_2 extends FlatSpecLike with Matchers {

var driver: WebDriver = null

@BeforeTest @throws[MalformedURLException]
def doBeforeTest{
val cap = DesiredCapabilities.chrome
val url = new URL("http://localhost:4444/wd/hub")
driver = new RemoteWebDriver(url, cap)
driver.manage().window().maximize()
}

@AfterTest
def doAfterTest{
driver.quit()
}

@test
def goto_staging (){
driver.get("https://www.amazon.com/");
System.out.println("Title of Amazon Home page: "+driver.getTitle() + "\n")

}

}
