When I try to update the \_source parameter in elastic search,I got an error. Can I change this settings?

```auto
PUT source-test
POST source-test/_mappings
{
  "_source" : {
      "enabled":true
  }
}
POST source-test/_mappings
{
  "_source" : {
      "enabled":false
  }
}

```

```auto
{
  "error" : {
    "root_cause" : [
      {
        "type" : "illegal_argument_exception",
        "reason" : "Mapper for [_source] conflicts with existing mapper:\n\tCannot update parameter [enabled] from [true] to [false]"
      }
    ],
    "type" : "illegal_argument_exception",
    "reason" : "Mapper for [_source] conflicts with existing mapper:\n\tCannot update parameter [enabled] from [true] to [false]"
  },
  "status" : 400
}

```

You need to set that enabled field when creating an index. You cannot change that setting at runtime.

See [\_source field | Elasticsearch Guide [7.13] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/7.13/mapping-source-field.html)
