Describe the bug

My supabase realtime listener stops receiving events after a while, without giving an errors.

To Reproduce

Here is the code snippet I'm using

async def realtime_insert_table_listener(table: str, cb: callable):
    while True:
        try:
            await async_supabase.realtime.connect()

            while not async_supabase.realtime.is_connected:
                await asyncio.sleep(0.2)

            channel = async_supabase.channel(table)
            channel.on_postgres_changes(
                event="INSERT",
                schema="public",
                table=table,
                callback=cb,
            )
            

            await channel.subscribe(
                lambda status, err: status
                == RealtimeSubscribeStates.SUBSCRIBED
                and logger.info("Successfully subscribed")
            )
            while True:
                await asyncio.sleep(10)
        except ConnectionClosedError as exc:
            logger.warning(
                "Connection closed unexpectedly: %s. Will retry...", exc
            )
        except Exception as exc:
            logger.exception(
                "Error in realtime listener: %s. Will retry...", exc
            )
        finally:
            try:
                if async_supabase.realtime.is_connected:
                    logger.info("Closing realtime connection...")
                    await async_supabase.realtime.close()
            except Exception:
                logger.exception("Error while closing realtime connection")

        # Backoff or small delay before attempting to reconnect
        logger.info("Will attempt to reconnect in 5 seconds...")
        await asyncio.sleep(5)

Can i take up this issue?

@ekorman how long before it stops receiving events? what environment are you running the code above in and how are you running it?

@silentworks i run it like this

asyncio.run(realtime_insert_table_listener(table=table, cb=cb))

inside a docker container (based on python:3.11-slim ) on an ubuntu VM.

hard to say exactly how long before it stops receiving events but seems like it works for between 12-36 hours before no longer receiving messages (or erroring) and never recovering.
