something wrong with BehaviorSubject for the socket.io #1

Hi, I reused part of your code from https://github.com/enaukkarinen/Angular2-RxJS-Socket.io-chat-application/blob/master/src/app/components/messaging/message.service.ts

` newMessage: Subject = new BehaviorSubject(null);

 this.newMessage.next(new Message(JSON.parse(msg)));

` But I got one error saying

Supplied parameters do not match any signature of call target. and one error saying undefined object because of newMessage is null

any ideas how to solve it ?

You need an object Type ... it can be Message Object or anything you like ... like ( string, number, any ) newMessage: Subject<Message> = new BehaviorSubject<Message>(null);
