Lets say I have .proto file like below:

```
service SvcOne{
    rpc MehtodOne(RequestOne) returns (ResponseOne) {}
}

service SvcTwo{
    rpc MethodTwo(RequestTwo) returns (ResponseTwo) {}
}

message RequestOne {
    string field_req= 1;
}

message ResponseOne {
    string field_res = 1;
}

message RequestTwo {
    string field_req= 1;
}

message ResponseTwo {
    string field_res = 1;
}

```

and then I try the code like below :

```
const server = new grpc.Server();      
server.addService(protoSchema.SvcOne.service, {MehtodOne: MethodOne});
server.addService(protoSchema.SvcTwo.service, {MethodTwo: MethodTwo});
server.bindAsync(
    "0.0.0.0:50051",
    grpc.ServerCredentials.createInsecure(),
    (err) => {
      if (err) {
        console.log("Error!");
      } else {
        routeServer.start();
        console.log("Server ready...");
      }
    }
  );

```

but got an error like this :

```
TypeError: Cannot read property 'service' of undefined

```

So I think I missing something in between.

**The question:**
How to bind multiple services (SvcOne & SvcTwo) in grpc-js server ? or is that not possible in grpc-js ?
