I was seeing the same issue. The problem only appears when using Chrome 65 (currently: dev channel). With Chrome 64 (both stable channel and beta channel) everything worked fine.

It turns out I had an old chromedriver installed. Specifically, I was using chrome=65.0.3325.51 with chromedriver=2.29.461585. Running npm install -g chromedriver bumped chromedriver to 2.35.528157 and now the problem is solved. Hope this helps!

TL;DR: run npm install -g chromedriver

The error says it all :

Your main issue is the version compatibility between the binaries you are using as follows :

• You are using chromedriver=2.33
• Release Notes of chromedriver=2.33 clearly mentions the following :

>Supports Chrome v60-62

• You are using chrome=65.0
• Release Notes of ChromeDriver v2.37 clearly mentions the following :

>Supports Chrome v64-66

So there is a clear mismatch between the ChromeDriver version (v2.33) and the Chrome Browser version (v65.0)

Solution

• Upgrade ChromeDriver to current ChromeDriver v2.37 level.
• Keep Chrome version at Chrome v65.x levels. (as per ChromeDriver v2.37 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.
• Execute your @Test.

The latest chrome browser requires corresponding latest chromedriver executable for the tests to run.

I have encountered the same issue and installed the chrome drive. Issue got resolved.

npm install chromedriver --chromedriver_version=LATEST

Changing latest version of ChromDriver worked for me.

You may need to update you driver the link for all the chromedriver updates are http://chromedriver.storage.googleapis.com/index.html make sure you chromedriver corresponds to your version of chrome

I simply installed a new version of Katalon Studio and it has worked fine.

This issue happens when chrome and chromedriver are not in sync. Either update both to the latest version or make sure they can work together. After running the following commands it worked for me

npm install -g chromedriver --chromedriver-force-download
webdriver-manager update
