We are using JIRA v6.2.7 with ScriptRunner v2.1.7, and today we are getting the error "Field 'issueFunction' does not exist or you do not have permission to view it.". This happens for all users we have tested. We have filters and dashboards using ScriptRunner scripts, and this has been working until today. To test this, when I try to create a filter, issueFunction is not available, but it is in the list of Custom Fields.
