Hi,
I skimmed through your code and it looks alright (perhaps I missed
something?). What line does throw in your case?
To answer your questions:
The response stream is ready immediately after starting your call and you
don't even need to send any requests nor close the request stream to be
able to read from responseStream (so your code really should work).
Also, if you need to just subscribe for server updates, perhaps the
bi-streaming call is an overkill - you could start a server-streaming call,
where you send a unary request (with you subscription details) and then
keep reading from the response stream (but your example should work).
