Before proposed fix:
static getDefaultAuthority(target) {
return target.path; // this returns "pubsub.googleapis.com:443"

After proposed fix:
static getDefaultAuthority(target) {
const hostPort = uri_parser_1.splitHostPort(target.path); // target.path is "pubsub.googleapis.com:443"
if (hostPort !== null) {
return hostPort.host; // this returns "pubsub.googleapis.com"
}
else {
throw new Error(`Failed to parse target ${uri_parser_1.uriToString(target)}`);

gRPC on Node.js
Implementations
For a comparison of the features available in these two libraries, see this document
C-based Client and Server
Directory: packages/grpc-native-core (lives in the grpc@1.24.x branch) (see here for installation information)
npm package: grpc.
This is the existing, feature-rich implementation of gRPC using a C++ addon. It works on all LTS versions of Node.js on most platforms that Node.js runs on.
Pure JavaScript Client
Directory: packages/grpc-js
npm package: @grpc/grpc-js
This library implements the core functionality of gRPC purely in JavaScript, without a C++ addon. It works on the latest version of Node.js on all platforms that Node.js runs on.
Other Packages
gRPC Protobuf Loader
Directory: packages/proto-loader
npm package: @grpc/proto-loader
This library loads .proto files into objects that can be passed to the gRPC libraries.
gRPC Tools
Directory: packages/grpc-tools
npm package: grpc-tools
Distribution of protoc and the gRPC Node protoc plugin for ease of installation with npm.
gRPC Health Check Service
Directory: packages/grpc-health-check
npm package: grpc-health-check
Health check service for gRPC servers.
