Hi Stephen,
I see you are deploying service from the same client node where proxy is
obtained.
In my setup, I have deployed service through ignite config on server start
and try to create a client later and hence the proxy. It works when I try
to obtain a proxy on the server node. But when I start a client node and
try to obtain service instance through proxy, it throws this exception
mentioned above
