Thanks Mr. Michael Lumish for your timely reply.
Actually I think that error is because I was calling server-side streaming
function as simple rpc function. So please ignore the previous error.
But when I tried to call correctly I got the below error. I guess below
error is caused because I'm not passing the correct parameters to
grpc.credentials.createFromMetadataGenerator
function

Below given is my program. I just wanted to know what is the input
parameter for grpc.credentials.createFromMetadataGenerator function.
Whether the parameter is metadata or access token?
Can you please explain me how to process the access token before passing it
to grpc.credentials.createFromMetadataGenerator function.
var metadata = new grpc.Metadata();
metadata.add('authorization', access_token);
console.log(metadata);
var auth_creds = grpc.credentials.createFromMetadataGenerator(metadata);
console.log(auth_creds);
var combined_creds = grpc.credentials.combineChannelCredentials(ssl_creds,
auth_creds);
var clientnew = new proto.Gateway('localhost:50001',combined_creds);
var cmd = {};
var call = clientnew.somefunction(cmd);
call.on('data', function(systems) {
console.log(systems);
});
