I am using JIRA Cloud Version and I am trialling the Project Automation plugin to automatically create some issues when a new Epic is created. On these automatically created issues I want to set the Epic Link (to the key of the parent Epic) and the fixVersions (to the fixVersions of the parent Epic). I can set the former via the Additional Fields JSON snippet, but I can't find the syntax that will do the job for the fixVersions. Any help hugely appreciated!
