client.send(data) disconnects clients on empty data

[ArmanJR]

We have a problem with client.Send() method; in client.OnSubscribe() method, when data is empty, client.Send(data) causes our clients to disconnect. To prevent this, we have added a length check:

if chatAccesses := clientData.GetProtoChatAccessesData(); len(chatAccesses) > 0 {
    client.Send(chatAccesses)
}

But it is much better if Centrifuge checks it.

Hello, I just tried to do it with Websocket/JSON case and centrifuge-js – and I don't observe disconnect, could you provide details about libs?

In general sending empty data may be a valid scenario in case of binary protocol format. So possibly simply rejecting empty data is not a way to go. But I'd like to understand which disconnect happens here.

Closing since no response from the op and I have not been able to reproduce
