ChromeDriver error “unknown error: cannot get automation extension”

Question

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 ext         


        

Answer 1

Updating your chrome driver exe would not actually fixed this issue, if you observed, it is happening while you're re-sizing chrome driver.Manage().Window.Maximize();

Try to comment this line and try again.

It's a quick fix, I'll update my answer once I find the root cause of this(however it seems because of browser update as nothing was changed in code for me).

Update: For me, it seems to be because of browser update as once I updated again this issue was gone.
