Joola SDK query syntax

[avif]

I'm trying to figure out the query syntax for the sdk, and I'm getting some unexpected behavior.
I'm tying to query all events where type = 'pageView'

My documents look like this:

{
    "type" : "pageView",
    "eventProps" : {
        "pageUrl" : "/"
    },
    "session" : "787a3fe9-4d43-965f-ac13-4b88d3c77e49",
}

And my query looks like this:

Joola.query.fetch({
    timeframe: 'this_day',
    interval: 'minute',
    metrics: [{
      key: 'type'
    }],
    filter: [
      ['type', 'eq', 'pageView']
    ],
    collection: 'analytics-dashboard'
}, function(err, results) {
    console.debug('results: ', results);
});

And the result:

[
  {
    "dimensions": [

    ],
    "metrics": [
      {
        "key": "type",
        "collection": "analytics-dashboard",
        "dependsOn": "type",
        "adhoc": true,
        "name": "type",
        "attribute": "type"
      }
    ],
    "documents": [
      {
        "type": {

        }
      }
    ],
    "uid": "PTB8766GMT5tFUcmO2oEtsqBMWMGOL2B",
    "resultCount": 1,
    "query": {
      "collection": "analytics-dashboard",
      "dontcache": true,
      "filter": [
        [
          "type",
          "eq",
          "pageView"
        ]
      ],
      "realtime": false,
      "interval": "timebucket.minute",
      "timeframe": {
        "start": "2016-01-09T00:00:00.000Z",
        "end": "2016-01-09T16:08:00.446Z"
      },
      "metrics": [
        {
          "key": "type",
          "collection": "analytics-dashboard",
          "dependsOn": "type",
          "adhoc": true,
          "name": "type",
          "attribute": "type"
        }
      ],
      "dimensions": [

      ],
      "uid": "PTB8766GMT5tFUcmO2oEtsqBMWMGOL2B",
      "ts": {
        "start": "2016-01-09T16:08:00.446Z",
        "end": "2016-01-09T16:08:00.449Z",
        "duration": 3
      }
    }
  }
]

As you can see, results[0].documents does not contain the queried documents
am I doing this right?
