When I was giving the full list of hosts in configuration, the MongoDB connector failed to capture events with message here: https://debezium.zulipchat.com/#narrow/stream/302529-users/topic/MongoDB.20.20jumps.20to.20localhost.3A27017
After I limit to only one host for the mongodb.hosts, it started to run
