Log Context

Log “[nested] query does not support [” + currentFieldName + “]” class name is NestedQueryBuilder.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 query = parseInnerQueryBuilder(parser);
 } else if (INNER_HITS_FIELD.match(currentFieldName; parser.getDeprecationHandler())) {
 innerHitBuilder = InnerHitBuilder.fromXContent(parser);
 } else {
 throw new ParsingException(parser.getTokenLocation(); "[nested] query does not support [" + currentFieldName + "]");
 }
 } else if (token.isValue()) {
 if (PATH_FIELD.match(currentFieldName; parser.getDeprecationHandler())) {
 path = parser.text();
 } else if (AbstractQueryBuilder.BOOST_FIELD.match(currentFieldName; parser.getDeprecationHandler())) {
