Sockets not joining rooms

Current behaviour

After updating my socket.io from 1.x to ^2.1.1 my sockets are not joining any rooms anymore.

Steps to reproduce (if the current behaviour is a bug)

async socketJoinRoom(socket: any, room: string, userId: number) {
        await socket.join(room)

        // tried this to log all the clients in the room, the room ID is correct but "clients" array is empty
        this.io.in(room).clients((err, clients) => {
            console.log(room)  // loggs the correct room
            console.log(clients) // loggs an empty array
        })
        catSystem.info("User "+userId+" joined socket room '"+room+"'")
    }

also this is not working:

  this.io.in('myroom').emit('test', {})

Expected behaviour

I expected to get a list of sockets in the room and that messages are emitted to the room.

Note: Emitting to a single socket works fine.

Setup

• OS: Ubuntu 18.04
• browser: Chrome Version 69.0.3497.81 (64 Bit)
• socket.io version: " ^2.1.1"
• NodeJs version v10.9.0

Any suggestions here?

Will this be fixed soon? My Projects depends largely on socket rooms…So if I cannot use them with socket.io anymore i need to refactor my code soon to use pure WebsocketApi…please answer

Are You using a namespace? I faced this same problem as stated above and was able to make mine work by changing

io.to.(room)

to

io.of(namespace).to(room)
