grpc-node: Express App crashing citing "Stream Removed"

Apologies in advance if this is on my end, struck out at StackOverflow and another resource using this package similarly.

I saw similar issues posted here in my search that were upstream resolutions.

Reproduction steps

grpc installed via npm for use in express app, application works fine in short-timeframe testing but eventually crashes in production tests.

Environment

• Ubuntu 18.04 LTS x64
• Node version 10.15.0 (also 10.13.0)
• grpc@1.17.0 via NPM (also tried --build-from-source)

Additional context

Usage context:

var lnrpcDescriptor = grpc.load("./rpc.proto");
var lnrpc = lnrpcDescriptor.lnrpc;
var lnd = new lnrpc.Lightning(hostport, credentials);
var call = lnd.subscribeInvoices(request)

call.on('data', function(response) {
  if (response.settle_index === '0') {
    console.log("New Invoice Issued: " + response.payment_request)
  }
  else {
    //iterate through array to find who paid their invoice and update the db
    for (var i = 0; i < loadedDB.db.Node.length; i++) {
      if (loadedDB.db.Node[i].add_index == response.add_index) {
        console.log("Node " + loadedDB.db.Node[i].Id + " has settled their invoice.");
        loadedDB.db.Node[i].isSettled = true;
        saveDB.writeEntry();
      }
    }  
  }  
});

call.on('status', function(status) {
  console.log(status);
});

call.on('end', function() {
  console.log('subscribeInvoices stream ended')
});
