I am afraid no error message was shown so I had to use a process of
elimination to figure it out.
Michael and the rest of the team: Do you have any advice on how I can
get this pure JS version of grpc running on nodeJS version on v8.6.0? I
am restricted for my current project with this version.
Version 8.6 supports http2 experimentally with the --expose-http2
command line argument. However, I cannot get the library to work. Any
help or workarounds you can offer? What features of 9.x or above does it
require specifically?
Thanks in advance!

It surprises me that that would be the problem, because the default
deadline is supposed to be infinitely far in the future. If it really
is timing out quickly, then that is a bug. Did you see any output that
indicated what the problem was?

Thanks for the speedy response Michael - I figured out the problem
myself in the end!
The issue was that when making a call to a remote GRPC server the
request times out too quickly.
In fact, even when I call a local server about 1/10 times my
request fails because the server couldn't respond in time. After
adding in a 5 second DEADLINE object to the calling command it
finally worked.
May I suggest increasing the default timeout of your GRPC routine?
Thanks!

Hello Michael,
Sorry to trouble you again, can you please help me by
checking the code below? It works fine under the native C++
wrapper but when I switch to the new pure JS version the
final call back never fires. Any help / direction would be
greatly appreciated.
