I have **ES7**. Currently the mapping looks like:

```auto
{
'mappings':
    {
     'properties': 
        {
        'aIndex': {'type': 'integer'},
        'AC': {'type': 'integer'},
        'AF': {'type': 'double'},
        ...
        },
    '_meta': {'gencodeVersion': '25', 'sourceFilePath': 's3://grch38_subset.vcf', 'genomeVersion': '38', 'sampleType': 'WGS', 'hail_version': '0.2.57'}
}

```

And it gives 400 Request error because it does not like keys inside \_meta:

`elasticsearch.exceptions.RequestError: RequestError(400, 'mapper_parsing_exception', 'Root mapping definition has unsupported parameters: [gencodeVersion : 25] [hail_version : 0.2.57] [genomeVersion : 38] [sampleType : WGS] [sourceFilePath : s3://grch38_subset.vcf]')`

Below is the full mapping inside mappings key:

Could you suggest on how I should change the mappings of the \_meta for it to work?

Hi @NLSVTN Just a bit of a syntax error you have the `"_meta"` at the wrong level it goes inside the `"mappings"` you have i outside.

```auto
PUT discuss
{
  "mappings": {
    "properties": {
      "aIndex": {
        "type": "integer"
      },
      "AC": {
        "type": "integer"
      },
      "AF": {
        "type": "double"
      }
    },
    "_meta": {
      "gencodeVersion": "25"
    }
  }
}

# Result
{
  "acknowledged": true,
  "shards_acknowledged": true,

It turned out that somehow an older version of ES was used even though we installed ES7, so adding additional level between `mappings` and `_meta` solved the issue:

```auto
'mappings': {
     'variant': {
          '_meta': {...}
      },
 },

```

Glad it works.. interesting that is different than the doc show [here](https://www.elastic.co/guide/en/elasticsearch/reference/7.17/mapping-meta-field.html)

Unless you are going all the way back to 6.X here and that is a bit different as well [here](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/mapping-meta-field.html)

Yeah, it looks like we can put all mapping under an arbitrary named `_doc`, not only `_doc`.

It is because version 6.X still support types and the type can be anything, but just one type per index, in your case it seems that the type name seems to be `variant`.
