[PYTHON] Timeout with websockets ConnectionClosedError: received 4300 (private use) Idle timeout expired; then sent 4300 (private use) Idle timeout expired

Trying to setup a heartbeat to keep the Notification websocket listener app that I am developing from crashing...

I am subscribing for session events and processing them in python just after time the app will fail with the above message.

I wonder what is the best way to do this... platform.refresh?

should I re-recreate the subscription on timeout vs sending a ping?

heartbeat_interval = 30  # in seconds

async def heartbeat(platform, interval):
    while True:
        try:
            platform.refresh()
        except ConnectionClosed:
            break
        await asyncio.sleep(interval)
