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...
