Mapper Attachments Plugin and SMILE

Elastic Stack Elasticsearch
1

Hello

I've got a problem working with Mapper Attachments Plugin.

This code

val json = XContentFactory.jsonBuilder().startObject()
    .field("file").startObject()
      .field("content").value(Base64.encodeBytes(bytes))
    .endObject()
  .endObject()

client.prepareIndex(indexName, typeName)
  .setSource(json).execute().actionGet()

works perfectly well, but when I change jsonBuilder to smileBuilder, ES
throws

org.elasticsearch.index.mapper.MapperParsingException: failed to parse

and when I try not to encode the file

val json = XContentFactory.smileBuilder().startObject()
    .field("file").value(bytes)
  .endObject()

or

val json = XContentFactory.smileBuilder().startObject()
    .field("file").startObject()
      .field("content").value(bytes)
    .endObject()
  .endObject()

ES throws

org.elasticsearch.index.mapper.MapperParsingException: No content is

I am using SMILE so I am curious if there is some workaround or am I doing
something wrong?

Thanks in advance
