Comienza en search.scala alrededor de la línea 75, donde se analiza la respuesta de la Elasticsearch API, y revisa el stack trace de JsonParser alrededor de JsonParser.scala. Reproduce o inspecciona respuestas que contengan el token '\u003c' reportado para determinar la ruta de respuesta que falla. El trabajo estará terminado cuando se incluya el manejo de esta respuesta sin la ParseException reportada.
