Runtime Error - event loop is closed - with authentication URL

[dazza-codes]

When using an authentication URL, like "redis://default:${REDISCLI_AUTH}@${REDIS_HOST_IP}:6379", the redis-cli makes a successful connection (i.e. the authentication works), but aioredis reports a lot of runtime errors about event loop closures (not sure if this a discussion point or a bug, it might be something in my code and not aioredis). The localhost redis-server (Ubuntu 20.04), when configured with default settings, runs fine with exactly the same aioredis code. Why would using an authenticated URL crash the aioredis connections or event loops?

redis server setup with authentication

sudo sed -i 's/protected-mode yes/protected-mode no/' /etc/redis/redis.conf
sudo sed -i 's/bind\s127.0.0.1/bind 0.0.0.0/' /etc/redis/redis.conf

# Redis is fast and millions of passwords can be checked per second, set a difficult password.
export REDISCLI_AUTH=MY_EXTREMELY_DIFFICULT_PASSWORD
sed -i "s/# requirepass.*/requirepass ${REDISCLI_AUTH}/" /etc/redis/redis.conf

# restart the service
sudo service redis-service restart
sudo service redis-service status

# confirm a connection works (this does work)
redis-cli -u "redis://default:${REDISCLI_AUTH}@localhost:6379"

sample aioredis code to get a connection

@dataclass
class AioRedisDB:

    redis_url: str = "redis://127.0.0.1:6379"
    jobs_db_n: int = 2
    max_connections: int = 1
    db_semaphore = asyncio.Semaphore(100)

    @property
    async def jobs_db(self):
        # need to instantiate redis-connection on-demand to avoid
        # Future <Future pending> attached to a different loop
        # TODO: lean how to optimize connections to auto-close them

        async with self.db_semaphore:
            return aioredis.from_url(
                self.redis_url,
                db=self.jobs_db_n,
                encoding="utf-8",
                decode_responses=True,
                max_connections=self.max_connections,
            )
