    Good afternoon. I have the following task.
    One Unity subscriber has the following components:
    BroadCast
    AudioStreamSender
    VideoStreamSender
    AudioStreamReceiver
    VideoStreamReceiver
    InputReceiver

    The second Unity subscriber has the following components:
    SingleConnection
    AudioStreamSender
    VideoStreamSender
    AudioStreamReceiver
    VideoStreamReceiver
    InputSender

    The server crashes with this message on connection:
    WebApp\UnityRenderStreaming-main\WebApp\build\class\websockethandler.js:117
    otherSessionWs.send(JSON.stringify({ from: connectionId, to: "", type: "answer", data: newAnswer }))
    ^

    TypeError: Cannot read properties of null (read 'send')

    at Receiver._write (C:\Users\buzakin\Desktop\WebApp\UnityRenderStreaming-main\WebApp\node_modules\ws\lib\receiver.js:83:10)

    When I remove the AudioStreamSender component from the second subscriber. Everything is ok!!!
    How can I solve this problem?

    That's strange.
    Looking only at the error log, it seems that the problem occurred because the SecondSubscriber side was disconnected.

    Can you also provide the logs for each of the Unity Subscriber1 and 2?
    And please describe your environment.(Unity version, package version, OS etc..)

    My environment:
    Unity 2021.3.15f1
    Windows 10 Pro
    RenderStreaming 3.1.0-exp.5.

    Yes! Weird. The error occurs when the subscriber in
    [SerializeField] private List<Component> streams = new List<Component>();
    the components are in this order:
    AudioStreamReceiver
    VideoStreamReceiver
    AudioStreamSender
    VideoStreamSender
    InputSender.

    This is the order in which everything works perfectly:
    AudioStreamSender
    VideoStreamSender
    AudioStreamReceiver
    VideoStreamReceiver
