We're using Yellowfin as our Business Intelligence (BI) tool. We had to upgrade to the latest version of Yellowfin. We were on Version 7.2 Build 20160426 and the latest version was Version 7.3 Build 20170907. When we ran the upgrade process, we received An error occured during installation: java.lang.NullPointerException. Yellowfin created a log file in the root directory. We've worked through the log file but couldn't identify the reason why we're receiving this error. After reading up, this was a bug in the latest build.
Fun Fact: An apple in the morning will keep you more awake than a cup of coffee.
Below is a print screen of the error we received:
