I am using several Automation rules running every minute to auto-transition issues based on a JQL Query. They all used to work, but some suddenly stopped transitioning issues.
Although the rules are enabled, and although the JQL query returns several results, the transition is not applied to these results. The transition is available in the current workflow state of the issues returned. The user executing the transition has maximum permissions in the project.
Disabling and enabling the rules seems to fix the issue... temporarily (thus it is not a permission issue).
I don't see any errors in the Jira logfile.
Why would transition available in the workflow not be applied to issues returned by a JQL query ?
