1). There are two ways to

sendData

from a

RoomServerClient

here, but I only see one of them referenced in the docs, are they both supported? I'm trying to send a data channel message with a

topic

via the

options

argument, but I'm not seeing the topic come through client side, it's always undefined. Let me know if code snippets would be helpful.

topics are not yet supported. we've added them to the protocol but server is not currently implementing them.

if you are using the chat prefab as is, then it will listen to a specific topic, which is

lk-chat-topic

defined here. you can customize that of course by creating your own chat with a different (or no) topic. The chat messages for the chat prefab also satisfy a chat message interface (here), so that the chat prefab understands them. AFAIK topics should (and do) work without a problem already from client to client. just server-sdk to client is not working as of now

Yeah I'm sending some data messages client to client and that seems to be working as expected Good to know on topics not being supported server side, do you have an idea of when they will be supported? Also thanks for looking into those empty chat messages!

@billions-summer-21168 there was a bug in the message handling that would lead to topics that were

undefined

to be interpreted as chat messages. This is fixed in

@livekit/components-react@1.0.5

. Cloud server support for topics should be available sometime this week!

Excellent, thank you for fixing that!
