[matt453]

I would like to be able to use the CLI version against one of the secondary nodes in our replicaSet. but if I pass it as an option I get errors

mongodb-schema mongodb://USERNAM:PASSWORD@HOST:PORT/AUTH_DB?slaveOk=true DATABASE.COLLECTION --no-values -n 100

/usr/local/lib/node_modules/mongodb-schema/node_modules/mongodb/lib/utils.js:132
      throw err;
      ^
