We are trying to migrate from Elasticsearch 6.7.1 to Elasticsearch 8.2.0.  
In Elasticsearch 6.7.1 it was possible to provide index-settings within an CreateIndexRequest as follows

```auto
{
    "index": {
      "mapping": {
        "total_fields": {
          "limit": 4000
        }
      }
    }
}

```

In Elasticsearch 8.2.0 it produces the following error

```auto
Exception in thread "main" co.elastic.clients.json.JsonpMappingException: Error deserializing co.elastic.clients.elasticsearch.indices.IndexSettings: Unknown field 'mapping' (JSON path: index.mapping) (line no=3, column no=16, offset=34)
	at co.elastic.clients.json.ObjectDeserializer.parseUnknownField(ObjectDeserializer.java:221)
	at co.elastic.clients.json.ObjectDeserializer.deserialize(ObjectDeserializer.java:178)
	at co.elastic.clients.json.ObjectDeserializer.deserialize(ObjectDeserializer.java:136)

	at co.elastic.clients.util.WithJsonObjectBuilderBase.withJson(WithJsonObjectBuilderBase.java:66)
	at co.elastic.clients.json.WithJson.withJson(WithJson.java:57)

```

As workaround i tried to set the _index.mapping.total\_fields.limit_ via the JAVA API Client via

```auto
builder.mappings( m -> m.totalFields( totalFields -> totalFields.limit( 4000 ) ));

```

but it also produces an error

```auto
co.elastic.clients.elasticsearch._types.ElasticsearchException: [es/indices.create] failed: [illegal_argument_exception] unknown setting [index.mappings.total_fields.limit] did you mean any of [index.mapping.total_fields.limit, index.mapping.nested_fields.limit, index.mapping.dimension_fields.limit]?
	at co.elastic.clients.transport.rest_client.RestClientTransport.getHighLevelResponse(RestClientTransport.java:281) ~[elasticsearch-java-8.2.0.jar:?]
	at co.elastic.clients.transport.rest_client.RestClientTransport.performRequest(RestClientTransport.java:147) ~[elasticsearch-java-8.2.0.jar:?]
	at co.elastic.clients.elasticsearch.indices.ElasticsearchIndicesClient.create(ElasticsearchIndicesClient.java:266) ~[elasticsearch-java-8.2.0.jar:?]

```

So how can i set value of _index.mapping.total\_fields.limit_ within an CreateIndexRequest?

Hi Alexander! It is happening to me also. It seems clearly to be a bug
