Problem description

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

HealthReportResponse health = myEsClient.healthReport();

Error:

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':

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
