linkedIssuesOf not found in the function registry

Mikael Falkvidd

I am using the JIRA Automation plugin to auto-transition JIRA Service Desk issues when their corresponding Development issue has been closed. The JQL used is

project = PT AND status = "Waiting for issue" AND issuefunction in linkedIssuesOf("project = MON AND status in ('Ready for release', 'Closed')", "is requested by")

This JQL worked yesterday, both in the Automation rule and in "Search for Issues". I even saved a filter with the expression so I know I am using the exact same expression.

Today the expression no longer works. In "Search for Issues" I get

Unable to find JQL function 'linkedIssuesOf(project = MON AND status in ('Ready for release', 'Closed'), is requested by)'.

In atlassian-jira.log I get the following every time the Automation rule is executed:

[jira.groovy.jql.ScriptedFunctionClauseFactory] Something has gone wrong: linkedIssuesOf not found in the function registry. Returning an empty query.

What could have caused the linkedIssuesOf function to disappear?

JIRA version: v6.3.15#634

Don't really know what is the cause for that.

But you can fix it -> Addons -> Script JQL Function
There you can click on the link "Scan" in the text at the beginning of the page
"If you have just added or removed a class for a script function, you can scan for them, otherwise they will be automatically loaded at startup."  

After that reload and it works again.
