Nested bulk

For this to work the data need to look like:

{
  "route": "test-route,
  "startData": datetime(2018, 1, 1, 10, 10, 10),
  "points": [
    {
        "segmentStart": 42,
        "longtitude": 0.12,
        "lattitude": 42.1
    }
  ]
}

and not like it does for you, which is just flat.

Hope this helps!

btw if you only ever expect one value for points field, and not a list, you don't need Nested and you should use Object instead.
