Is this the case ? "MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD environment variables, it will make mongod running with the --auth option" If so you may have to enable mongoose authentication in the mongoose (this link may help https://stackoverflow.com/questions/26694824/how-to-authenticate-mongoose-connection-mongodb-in-node-js)
