We used below link for reference:

Did some research and found that issue might be related to missing commons-lang.jar but commons-lang3-3.1.jar is already present under /opt/yellowfin/appserver/webapps/ROOT/WEB-INF/lib.

We tried with commons-lang-2.6.jar, commons-lang3-3.4.jar, commons-lang3.jar but none of them worked.

Below is the complete stack trace:
