"WebsocketStreamClientImpl - null" messages in the log

[lz-44]

From time to time, I can see the following non-descriptive messages in the log:
18:14:44.889 [OkHttp https://stream.bybit.com/...] ERROR c.b.a.c.w.i.WebsocketStreamClientImpl - null

Presumably, these messages occur after websocket session is terminated with error.
I also assume it may be logged from here:

public void onError(Throwable t) {
    LOGGER.error(t.getMessage());
}

(WebsocketStreamClientImpl.java:283)

Would be great at least to have some more descriptive and meaningful messages. Maybe also good idea to include smth like WS session id across logs for tracing purposes.

Thanks!
