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.
process.env.GRPC_SSL_CIPHER_SUITES='ECDHE-ECDSA-AES128-GCM-SHA256'
// Old Way: var grpc = require('grpc');
vargrpc=require('@grpc/grpc-js');
varfs=require("fs");
varprotoLoader=require("./proto-loader.js");
varlndCert=fs.readFileSync("/Users/patrickchugh/Dropbox/Dev/nodejs/tls.cert");
varmacfile=fs.readFileSync("/Users/patrickchugh/Dropbox/Dev/nodejs/admin.macaroon");
varmacaroon=macfile.toString('hex');
letmetadata=newgrpc.Metadata();
metadata.add('macaroon',macaroon);
letmacaroonCreds=grpc.credentials.createFromMetadataGenerator((params,callback)
=>
callback(null,metadata)
);
//Combine SSL + macaroon metadata in the headers
varsslCreds=grpc.credentials.createSsl(lndCert);

varpackageDefinition=protoLoader.loadSync('rpc.proto', []);
varlnrpcDescriptor=grpc.loadPackageDefinition(packageDefinition);
varlnrpc=lnrpcDescriptor.lnrpc;
varlightning=newlnrpc.Lightning('34.232.232.166:10009

lightning.getInfo({}, function(err,response) {
console.log('GetInfo:',response);
});
