Hello, currently using elasticsearch-java 8.1.3 client to communicate with my es cluster. Index settings looks like this: ` "settings": { "index": { "number_of_shards": 1, "number_of_replicas": 7, "allocation.max_retries": 15 } }`

According to the documentation, allocation.max\_retries is still a valid setting but it's missing from co.elastic.clients.elasticsearch.indices.IndexSettings and `Exception: co.elastic.clients.json.JsonpMappingException: Error deserializing co.elastic.clients.elasticsearch.indices.IndexSettings: Unknown field 'allocation.max_retries' (JSON path: index['allocation.max_retries']) (line no=1, column no=56, offset=55)` is thrown when deserializing. Is this a mistake or I'm doing something wrong?

Welcome!

There is a workaround explained in this documentation.

But my issue is not that the field is required and not received. The field does not exist and it is received. I tried: `objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);` but this did not fix my issue.

Found the issue. Exception is thrown when indexSettings object is created. Issue: `indexSettings = settingsJson != null ? IndexSettings.of(i -> i.withJson(IOUtils.toInputStream(finalSettingsJson.toString(), StandardCharsets.UTF_8))) : null;`

Fix:

```auto
  var mapper = SimpleJsonpMapper.INSTANCE;
indexSettings = settingsJson != null ? IndexSettings.of(i -> i.withJson(mapper.jsonProvider().createParser(IOUtils.toInputStream(finalSettingsJson.toString(), StandardCharsets.UTF_8)), mapper)) : null;

```

Any solution like this one for version 7.x?

I believe so. [MissingRequiredPropertyException in a response | Elasticsearch Java API Client [7.17] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/7.17/missing-required-property.html)
