Bulk API with nested mapping (non DSL)

Elastic Stack Elasticsearch
1

I wrote a script to load data to an elasticsearch instance using bulk helpers. It works great with simple mappings like this one:

{
    "mappings": {
        "*": {
            "properties": {
                "id": {"type": "long"},
                "description": {"type": "text"},
                "active": {"type": "boolean"}
            }
        }
    }
}

But when I try using a nested mapping, it doesn't work right.

I have a data file with this header route|startDate|segmentStart|longitude|latitude ('|' is the delimiter) and this mapping:

{
  "mappings": {
    "*": {
      "properties": {
        "route" : {"type": "text"},
        "startDate" : {"type": "date"},
        "points": {
          "properties": {
            "segmentStart": {"type": "integer"},
            "longitude": {"type": "float"},
            "latitude": {"type": "float"}
          }
        }
      }
    }
  }
}

As you can see "points" has three properties "longitude", "latitude" and "segmentStart". But the mapping I see after uploading the data is this one:

{
  "shape": {
    "mappings": {
      "*": {
        "properties": {
          "latitude": {"type": "text", "fields": {"keyword": {"type": "keyword", "ignore_above": 256}}},
          "longitude": {"type": "text", "fields": {"keyword": {"type": "keyword", "ignore_above": 256}}},
          "points": {
            "properties": {
              "latitude": {"type": "float"},
              "longitude": {"type": "float"},
              "segmentStart": {"type": "integer"}
            }
          },
          "route": {"type": "text"},
          "segmentStart": {"type": "text", "fields": {"keyword": {"type": "keyword", "ignore_above": 256}}},
          "startDate": {"type": "date"}
        }
      }
    }
  }
}

And the data is clearly not uploaded in the way I need. Any ideas about what could be wrong?
