Unable to take Screen Shoot on test failure

Question

I've been having trouble with taking screenshot on failure when I run my Automation project.

This is the error I am getting in my Extent report:

My mistake was in customListeners class, I had to delete Webdriver driver = null; — MitkoPo, Feb 16 '22 at 08:55
