Code:

This error message...

org.openqa.selenium.SessionNotCreatedException: Message:  Could not start a new session. Response code 500. Message: session not created:
.
Driver info: org.openqa.selenium.chrome.ChromeDriver

...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context i.e. google-chrome session.

Your main issue is the incompatibility between the version of the binaries you are using as follows:

• You are using chrome=99.0
• Release Notes of ChromeDriver v99.0 clearly mentions the following :

Supports Chrome version 99

• But your chromedriver version is not getting detected.

Driver info: org.openqa.selenium.chrome.ChromeDriver

• Your JDK version 1.8.0_281 is also old and ancient.

So most possibly there is a mismatch between jdk version, chromedriver version and the chrome=99.0

Solution

Ensure that:

• JDK is upgraded to current levels JDK 8u311.
• ChromeDriver is updated to current ChromeDriver v99.0 level.
• Chrome Browser is updated to current chrome=99.0 (as per chromedriver=99.0.4844.51 release notes).
