Commencez dans search.scala vers la ligne 75, où la réponse de l'Elasticsearch API est analysée, et examinez la trace de la pile de JsonParser autour de JsonParser.scala. Reproduisez ou inspectez les réponses contenant le token '\u003c' signalé afin de déterminer le chemin de réponse qui échoue. Le travail sera terminé lorsque cette réponse sera gérée sans la ParseException signalée.
