Log Context

Log “Nested type [” + name + “] does not support [subobjects] parameter” class name is NestedObjectMapper.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 public static class TypeParser extends ObjectMapper.TypeParser {
 @Override
 public Mapper.Builder parse(String name; Map node; MappingParserContext parserContext)
 throws MapperParsingException {
 if (parseSubobjects(node).explicit()) {
 throw new MapperParsingException("Nested type [" + name + "] does not support [subobjects] parameter");
 }
 NestedObjectMapper.Builder builder = new NestedObjectMapper.Builder(name; parserContext.indexVersionCreated());
 parseNested(name; node; builder);
 for (Iterator> iterator = node.entrySet().iterator(); iterator.hasNext();) {
 Map.Entry entry = iterator.next();
