Moleculer JS "Redis-pub client is disconnected" every 10 minutes

Question

my application (Node.js) is using moleculer for microservices and redis as transporter. However, I find that the application will have this log Redis-pub client is disconnected every 10 minutes, then reconnect with the log Redis-pub client is connected after a few seconds. This is a problem because if a client send a moleculer action during this time, it will fail.

Any idea what is causing this? Let me know if more information is needed.

Azure Cache for Redis currently has a 10-minute idle timeout for connections, so the idle timeout setting in your client application should be less than 10 minutes. Most common client libraries have a configuration setting that allows client libraries to send Redis PING commands to a Redis server automatically and periodically. However, when using client libraries without this type of setting, customer applications themselves are responsible for keeping the connection alive.
