final mapping would have more than 1 type

I am trying to do full text search on rethinkdb. I took this package for a spin. I am getting the following error.

Rejecting mapping update to [ta3] as the final mapping would have more than 1 type

rethinkdbElasticsearchStream({
    backfill: true,
    elasticsearch: { host: '127.0.0.1', port: 9200 },
    rethinkdb: { host: '127.0.0.1', port: 28015 },
    tables: [
      { db: 'db1', table: 'lectures' },
      { db: 'db1', table: 'speakers' },
      { db: 'db2', table: 'clipnshare' }
],
    watch: true
  });
  return elastic;
};

I am pretty new to elastic search but would venture to guess that this is related to this es update

Do you have any plans on updating this repo?

What do you suggest?

gsandf / rethinkdb-elasticsearch-stream
