Long Poll Request Error in Swift when Connecting to SocketIO

I am attempting to connect to Online-Go SocketIO in Swift using Starscream Websocket(https://github.com/daltoniam/Starscream). My URL and values passed in are correct; however, after running my code, I received an “error during long pull request” log. I wonder how should I fix the problem, thank you so much!

func connectToGame(tokenType: String, accessToken: String, gameID: Int, playerID: Int, chat: Bool) {
    private var manager = SocketManager(socketURL: URL(string: "https://online-go.com/socket.io")!, config: [.secure(true), .log(true), .compress])
    let socket = manager.defaultSocket

    socket.on(clientEvent: .connect) { data, ack in
        print("socket connected")
        socket.emitWithAck("authenticate", "\(tokenType)  \(accessToken)").timingOut(after: 5) { dataArray in
            print(dataArray)
        
        socket.emit("game/connect", ["game_id": gameID, "player_id": playerID, "chat": chat])
        }
    }
    socket.connect()
}

The log message after running the code is like the following:

In log it says you are using polling transport. Need to use websocket.

May I ask what should I do to change the connection to WebSocket? Thank you so much!

After quick search in docs, I’m guessing add .forceWebsockets(true) to config?
Sorry, haven’t used this library or Swift before.
