#265 Exception when trying to publish data Issue created by davidliu Hello, I always get the Exception when trying to publish data with android sdk(v1.2.2.), it doesn't help trying to switch the reliability type to LOSSY, I also get the message: channel not established, this is the Exception I get:
io.livekit.android.room.track.TrackException$PublishException: channel not established for RELIABLE
This is the method I use:
Copy code
data = data, // ByteArray
                    reliability = DataPublishReliability.RELIABLE,
                    destination = listOf(sId),
                    topic = null
                )
Is there anything else I should do in order to config the underlying data channels, or any other type of configuration? As far as I've seen, both data channels should be initialized when we call connect(). Just for clarity, I'm not trying to call publishData() as soon as I call connect(). Every help is appreciated! 🙏 [Slack Message](https://livekit-users.slack.com/archives/C01KVTJH6BX/p1694085116540669?thread_ts=1694085116.540669&amp;cid=C01KVTJH6BX) ``` livekit/client-sdk-android
