I have a shell action node that is able to send notifications to a chat application and can be used as a transition route if another action node in the workflow fails. What I'd like to be able to do, is use wf:user() and wf:lastErrorNode() in that notification. My idea was to pass these values to my shell script as arguments, but when I place 'wf:X()' as the argument to my shell action node, it doesn't resolve to anything and just gives me the raw string as the argument. Is there a way to use these in a shell action node?
