Answer
The error you received most probably relates to the Java version that your instance is running on. We built our add-ons in accordance with the current supported Java platform by Atlassian. More information can be read here: Supported Platforms
First, check the Java version your instance is running on:
Code Block java -version
If the version you're running is lesser than what is recommended by Atlassian in the Supported Platforms page, upgrade your Java to the advised version.
