Hi, I'm having trouble doing a bulk index request using the java 8.1.1 client. I get an unclear error message and I'm basically stuck. ```auto String test= "{ \"test\",\"test\"}"; final InputStream jsonInputStream = new ByteArrayInputStream(test.getBytes()); final ElasticsearchClient client = instanceManager.getClient(); final BulkResponse response = client.bulk(br -> br.operations( bo -> bo.index(io -> io.withJson(jsonInputStream).index("test").id("1")) )); ``` I get the following cryptic error upon execution: ```auto java.lang.IllegalArgumentException: Class class co.elastic.clients.elasticsearch.core.bulk.IndexOperation cannot be read from JSON at co.elastic.clients.util.WithJsonObjectBuilderBase.withJson(WithJsonObjectBuilderBase.java:46) at co.elastic.clients.json.WithJson.withJson(WithJson.java:43) ... ``` I assume that there is something wrong with my json, but the [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html) unfortunately doesn't list a java example. Can someone please help in providing a working example? ---

I saw that the error occurs because the mapper doesn't deserialize the class because it doesn't have the @JsonpDeserializable annotation. Maybe you have to mount an object instead of reading a json. ---

try this: ```auto var operations = BulkOperation.of(bo -> bo.create(CreateOperation.of(co-> co.document(Product.builder().title("none").build())))); BulkRequest bulkRequest = BulkRequest.of(br ->br.operations(operations).index("index_alias")); final BulkResponse response = client.bulk(bulkRequest); ``` ---

There is no 'Product' builder in the 8.1.1 API it seems, what import are you using? In my particular case; I'm getting json files delivered which represent a document, but it would mean I'd have to parse them and rebuild them using the builder. ---

We've recently added [documentation for sending bulk requests](https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/indexing-bulk.html) with the Java API client. There indeed an issue in bulk request operations that causes `withJson` to fail (the nd-json encoding is a special case that was missing a test). I opened [Bulk request operations fail on withJson · Issue #251 · elastic/elasticsearch-java · GitHub](https://github.com/elastic/elasticsearch-java/issues/251) for this. A workaround is to use Jackson's `com.fasterxml.jackson.databind.util.RawValue` for the bulk operation's document. ---

Dear, I'm facing the same error while trying to index a JSON with `withJson` method. I tried to use `RawValue` but still having an error when sending the request to the server: > BulkRequest.Builder br = new BulkRequest.Builder(); > String json = "{my\_json\_value}"; > br.operations(op -\> op.index(idx -\> idx.index(index).id(id).document(new RawValue(json)))); > BulkRequest request = br.build(); > BulkResponse response = getClient().bulk(request); The error is: > co.elastic.clients.elasticsearch.\_types.ElasticsearchException: [es/bulk] failed: [illegal\_argument\_exception] Malformed action/metadata line [3], expected START\_OBJECT but found [VALUE\_STRING] So I think that `RawValue` doesn't work... Thanks ---

Well, I finally get it with following code 😉 ```auto String json = "my_json_value"; Reader reader = new StringReader(json); JsonpMapper jsonpMapper = getClient()._transport().jsonpMapper(); JsonProvider jsonProvider = jsonpMapper.jsonProvider(); JsonData jd = JsonData.from(jsonProvider.createParser(reader), jsonpMapper); BulkRequest.Builder br = new BulkRequest.Builder(); br.operations(op -> op.index(idx -> idx.index(index).id(id).document(jd))); BulkRequest request = br.build(); BulkResponse response = getClient().bulk(request); ``` ---
