Trying to perform issue workflow actions are resulting in an error similar to:

Could not load FunctionProvider class. Error when changing state from "In Progress"

The following appears in the atlassian-jira.log:

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  JRA-44732 - Getting issue details... STATUS  has been raised to improve this functionality.


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

(info) 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.
