Since the 7th of February all my tests are failing with the same error; the log entry reads:
RESPONSE MaximizeWindow unknown error: cannot get automation extension
from unknown error: page could not be found: chrome-extension://aapnijgdinlhnhlmodcfapnahmbfebeb/_generated_background_page.html
(Session info: chrome=57.0.2987.21)
I'm not sure if this is caused by a Chrome update or something else - the message is vague enough as it is.
EDIT: I am using C#, and the latest Chromedriver.
Suddenly got this error -> Additional information: unknown error: cannot get automation extension from unknown error: page could not be found: chrome-extension..
This issue exists even when using ChromeDriver 2.29
What solved it though was removing this line.
A quick fix but really not the one I've been looking for. Would be great to still use the sizing mechanism.
it supports the higher versions of chrome driver 2.29.
pls. find the latest chrome drivers in http://www.seleniumhq.org/download/
