TCP Request Node - not flowing out

When TCP Request node is set to return 'immadiately' (socket does not respond), flows after TCP Request node do not fire. Is this expected?

And how are the debug nodes configured ?

Not much there, just a OK/NOK message.

ok/nok ... where do you see this ?

You are capturing done only from the payload, what if it outputs something else ?
Change the debug node to output complete msg object. (both debug nodes)

I'm capturing a literal "done". setting 'complete msg object' exhibits same behavior, no output.
