Hi All,

I m trying to update a nested field using java high level client .
Here i am using script to update the document . While executing it its throwing error which i have mentioned below.

CODE :

                    RestHighLevelClient esClient = new RestHighLevelClient(
			  RestClient.builder(new HttpHost("localhost",9200)));

                    UpdateRequest updateRequest = new UpdateRequest("my_index", "_doc", "1");
		
		Map<String, Object> parameters = new HashMap<String, Object>();
		
		parameters.put("key", "value or any java pojo");

		Script inline = new Script(ScriptType.INLINE, "painless",
		        "ctx._source.notes.add(params.key)", parameters);  
		updateRequest.script(inline);
		
		UpdateResponse updateResponse =  esClient.update(updateRequest);
		
		System.out.println("results : "+updateResponse.getId());
		
		esClient.close();

ERROR :

Have you tried running the same request using curl to understand whether it's a client issue or your request has something wrong in it?
