Answer 1

The error says it all :

org.openqa.selenium.WebDriverException: unknown error: cannot determine loading status
from unknown error: missing or invalid 'entry.level'

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

• You are using chromedriver=2.29.461591
• Release Notes of chromedriver=2.29.461591 clearly mentions the following :

Supports Chrome v56-58

• You are using chrome=63.x
• Release Notes of ChromeDriver v2.34 clearly mentions the following :

Supports Chrome v61-63

• Release Notes of ChromeDriver v2.35 clearly mentions the following :

Supports Chrome v62-64

• You are using Selenium Version 3.5.3.
• Your JDK version is 1.8.0_131.

So there is a clear mismatch between the chromedriver version (v2.29.4) [which supports Chrome v56-58] with the Chrome Browser version (v63.x) [supported by ChromeDriver v2.34 minimum]

Solution

• Upgrade JDK to recent levels JDK Version 8 Update 151.
• Upgrade Selenium to current levels Version 3.8.1.
• Upgrade ChromeDriver to ChromeDriver v2.35 level.

• Keep Chrome to Chrome v64.x levels. (as per ChromeDriver v2.35 release notes)

• Execute your Test.
