Malformed Json for an object with a rawfield only using XContentBuilder

Elastic Stack Elasticsearch

Hi,

I couldn't find a way to create a valid document using the XContentBuilder
including a raw field only.

Following the code I used:

  jsonStr = "{\"field\":\"value\"}";
  XContentBuilder xb = jsonBuilder()
      .startObject()
      .rawField("object_name", jsonStr.getBytes())
   .endObject();

This code resulted in a malformed json document { , "object_name" :
{"field":"value"} }. Looking at the JsonXContentGenerator implementation of
writeRawField it looks like this is what the code is expected to do, in
fact:

@Override
public void writeRawField(String fieldName, byte[] content,

OutputStream bos) throws IOException {
generator.writeRaw(", "");
generator.writeRaw(fieldName);
generator.writeRaw("" : ");
flush();
bos.write(content);
}

In order to overcome this I had to add a dummy empty field to the document:

  XContentBuilder xb = jsonBuilder()
      .startObject()
      .field("dummy", "")
      .rawField(DOC_OBJECT_NAME, jsonStr.getBytes())
   .endObject();

I wonder if there is any other method allowing to add a raw field only to a
document using XContentBuilder or not.

Thank you in advance,

Andrea
