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
{
"index": {
"mapping": {
"total_fields": {
"limit": 4000
}
}
}
}
In Elasticsearch 8.2.0 it produces the following error
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)

As workaround i tried to set the index.mapping.total_fields.limit via the JAVA API Client via
builder.mappings( m -> m.totalFields( totalFields -> totalFields.limit( 4000 ) ));
but it also produces an error
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]?

So how can i set value of index.mapping.total_fields.limit within an CreateIndexRequest?
