There is a third-party function on the workflows that the JIRA application expects to find there. When it goes to access that plugin, it fails, and throws the above exception. This happens as the Java Class Loader can't find the plugin - in this example it is the JIRA Suite Utilities plugin and the error is occurring as it is not installed. The suggestion JRASERVER-44732 - Improve error when workflow has missing add-on has been raised to improve this functionality.
Resolution
Re-install the plugin:
Log in as a Jira Administrator user
Navigate to the page ⚙ > Manage apps > Find new apps
Search for the add-on JSU Automation Suite for Jira Workflows
Install it
ℹ️ If you no longer want to make use of the plugin and its functions, it is still necessary to re-install the plugin. You will then access your workflow and remove all workflow functions associated with the plugin.
