Workflow transition fails with this message in the atlassian-jira.log:

http-8080-1 ERROR username 740x536x1 b9x4u0 /secure/CommentAssignIssue.jspa [atlassian.jira.workflow.OSWorkflowManager] Caught exception while attempting to perform action 171 from workflow 26206 on issue 'TST-1234'
com.opensymphony.workflow.WorkflowException: Could not load validator class


For troubleshooting it you can check the logs and export the workflow as XML.


Workflow has an action as a validator that refers a specific class, and this class comes from a third party plugin. It can happen with different plugins use validator class.

(info) i.e: com.innovalog.jmwe.plugins.validators.CommentRequiredValidator


(info) There are three ways to fix it:

  • Suggestion 1:
    • Install the latest compatible version of this plugin.
  • Suggestion 2:
    • Remove the validator that refers to this plugin from your workflow.
  • Suggestion 3:
    • Check in the workflow what step is using this post-function as a validator class. You may can remove if it's unnecessary validator.
