I'm not sure if this is by design or not, but link calls aren't working for me inside subflows.
Outside of a subflow, the configuration below works just fine. Inside a subflow (replace the inject node with the input node of the subflow) it doesn't work at all. Neither of the debug nodes print to the console, and the link call times out.
Is this a bug, or is this by design for some odd reason?
