I developed a app to read some web pages using Selenium.

ChromeDriver on windows worked correctly but in unix base Oss (Mac & Centos7) does not worked!

I think a problem is "Forwarding newSession on session null to remote" in the unix base OSs.

Some warnings and info when I ran app in unix base OSs are as bellow:

Starting ChromeDriver 102.0.5005.61 (0e59bcc00cc4985ce39ad31c150065f159d95ad3-refs/branch-heads/5005@{#819}) on port 53751
Only local connections are allowed.
Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.
ChromeDriver was started successfully.
[1658989503.540][WARNING]: This version of ChromeDriver has not been tested with Chrome version 103.

You may need to include a dependency on a specific version of the CDP using something similar to `org.seleniumhq.selenium:selenium-devtools-v86:4.1.0` where the version ("v86") matches the version of the chromium-based browser you're using and the version number of the artifact is the same as Selenium's.

Are there any solutions to resolve ChromeDriver error?

If you have any suggestions that can be help me, please add comment or answer.

Thanks.

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

Your main issue is the incompatibility between the version of the binaries you are using.
