Error retrieving a new session from the selenium server

This is a generic error, there could be many situations which could lead to this. For me, when I updated my Google Chrome and suddenly my automation I hit this error. Here is how I solved it.

Solution

Get the latest chromedriver (https://sites.google.com/a/chromium.org/chromedriver/)
Make sure your automation framework uses the latest chromedriver

For projects using node.js, nightwatch.js, running on Mac OS use the following steps

Update the package.json
npm update

Replace

/<PWD>/node_modules/chromedriver/bin/chromedriver

With

/<PWD>/node_modules/chromedriver/lib/chromedriver/chromedriver
