Answer 1

The error says it all WebDriverException: unknown error: cannot get automation extension

As per your Error Stack Trace you are using :

• chromedriver=2.29
• chrome=62.0

The Release Notes of chromedriver=2.29 clearly mentions the following :

Supports Chrome v56-58

The Release Notes of chromedriver=2.33 clearly mentions the following :

Supports Chrome v60-62

Solution :

The solution will be either to upgrade chromedriver binary to v2.33 levels or to downgrade your Chrome Browser binary to v56-58
