Inline document enhancement

I have the following strucutre doc

{
    "_id" : "NmBYYasdsa",
    "objectId" : "asdsd"
    "text" : "test",
    ....
    "publishedAt" : ISODate("2015-05-28T15:31:51Z"),
    "updatedAt" : ISODate("2015-05-28T15:31:51Z"),
    "data" : {
        .....
        "likeCount" : 0,
        "replyCount" : 0
    }
}

      

        
        
        
      

    

This is used to keep my database in sync with the external API. To do this, I go through the API once a minute and do a bulk update, matching the object id to update my database.

The problem is that the subdocument is data

not updated on update, any ideas as to why?

My Bulk Printing Technique

Mongo.Collection.prototype.upsertBulk = function(matcher, documents, options) {
  if (_.isEmpty(documents)) { throw Error('Empty list of documents provided'); }
  options = options || {};

  var operations = documents.map(function(_document) {
    _document._id = Random.id();

    var operation = {
      updateOne: {
        filter: {},
        update: { $set: _document },
        upsert: true
      },
    };
    operation['updateOne']['filter'][matcher] = _document[matcher];

    return operation;
  });

  this.__mongoCollection(function(collection) {
    collection.bulkWrite(operations, options, function(error, result) {
      if (error) { throw error; }
      return result;
    });
  });
};
