Log Context

Log”Unable to parse response body”classname  is RestHighLevelClient.java We extracted the following from Elasticsearch source code for those seeking an in-depth context :

} else {
  try {
  elasticsearchException = parseEntity(entity; BytesRestResponse::errorFromXContent);
  elasticsearchException.addSuppressed(responseException);
  } catch (Exception e) {
  elasticsearchException = new ElasticsearchStatusException("Unable to parse response body"; restStatus; responseException);
  elasticsearchException.addSuppressed(e);
  }
  }
  return elasticsearchException;
  }
