The code here...

metricq-sink-websocket/metricq_sink_websocket/views.py

Lines 24 to 38 in 1f51f61

	try:
	msg_data = json.loads(msg.data)
	if msg_data["function"] == "subscribe":
	new_metrics = set(msg_data["metrics"])
	metadata = await sink.subscribe_ws(ws, new_metrics - metrics)
	await ws.send_metadata(metadata)
	metrics |= new_metrics
	except Exception as e:
	logger.error(
	"error during message handling {}: {}\n{}",
	type(e),
	e,
	traceback.format_exc(),
	)
	break

...breaks out of the websocket message loop, but does not result in app termination. Exceptions of type RPCError should most likely be fatal.
