I'm using `co.elastic.clients:elasticsearch-java:8.13.4` and get a deserilizing error calling the healthReport() method:

```auto
HealthReportResponse health = myEsClient.healthReport();

```

Error:

```auto
co.elastic.clients.json.JsonpMappingException: 
Error deserializing co.elastic.clients.elasticsearch.core.health_report.SlmIndicator:
 co.elastic.clients.util.MissingRequiredPropertyException:
 Missing required property 'SlmIndicatorDetails.unhealthyPolicies' (JSON path: indicators.slm.details) (line no=1, column no=1294, offset=-1)

```

Debugging **ElasticsearchTransportBase** shows the response 'resp':

```auto
requestLine: GET /_health_report HTTP/1.1

```

is OK (`HTTP/1.1 200 OK`) I can also call this over REST and get some JSON, however your deceriliser breaks...

The value of **content** at line `ElasticsearchTransportBase:396`

```auto

Hello, thanks for reporting this! It's a problem with the [API specification](https://github.com/elastic/elasticsearch-specification) used to produce the client code, the property `unhealthy_policies` is set as "required", but it shouldn't be. If you want you can create a new issue in the [java client repo](https://github.com/elastic/elasticsearch-java).
