MongoDB as session storage

I’m attempting to use mongodb as session/object storage for a docker swarm using these instructions https://docs.lucee.org/guides/extensions/extension-mongoDB.html but I’m not seeing anything in the tailed log when I start a session. I do see lucee making an initial connection to mongo in the log. Do I need to do anything special here? I am using coldbox - maybe the server defaults are getting overridden? ( @ bdw429s )
