getFieldMapping request using java API for elasticsearch

Elastic Stack Elasticsearch
1

I am trying to replicate below query DSL using java:

GET /test/_mapping/field/*?include_defaults=true

I am using below code to get mappings:

GetFieldMappingResponse resp = client.indices().getFieldMapping(new GetFieldMappingRequest.Builder()
					.index("test").fields("*").includeDefaults(true).build());

When i execute this code I get error:

co.elastic.clients.json.UnexpectedJsonEventException: Unexpected JSON event 'VALUE_NULL' instead of '[START_OBJECT, KEY_NAME, VALUE_STRING]'

If I make "includeDefaults" as "false" in API request, I get results but get error if I make it true.

Below is the response of mentioned DSL if I do it from UI:

GET /test/_mapping/field/*?include_defaults=true
