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.

Thanks Simon! 

There were no functions listed before the scan and the scan added 23 functions. The function is now accessible both in "Search for issues" and in the Automation plugin.
