This is usually caused by a mismatch in versions between Chrome (the browser) and Chrome WebDriver.

Try updating them: Tools > Update WebDrivers

hi Thomas,

thanks for the help, i tried this multiple times but didn’t work even i changed ChromeDriver Manually also but its as ease.

duyluong · October 13, 2020, 12:43pm

@gunjan_mishra

Just let Chrome updates completely, restart your machine then try running again.

Thanks

gunjan_mishra · October 14, 2020, 5:43am

Yeah, like “Turn it off and turn it on again… no, off again and then on again…”
