Log Context

Log “[nested] nested path [” + path + “] is not nested”classname  is NestedAggregationBuilder.java We extracted the following from Elasticsearch source code for those seeking an in-depth context :

return new NestedAggregatorFactory(name; null; null; queryShardContext;
 parent; subFactoriesBuilder; metadata);
 } 
 if (childObjectMapper.nested().isNested() == false) {
 throw new AggregationExecutionException("[nested] nested path [" + path + "] is not nested");
 }
 try {
 ObjectMapper parentObjectMapper = queryShardContext.nestedScope().nextLevel(childObjectMapper);
 return new NestedAggregatorFactory(name; parentObjectMapper; childObjectMapper; queryShardContext;
 parent; subFactoriesBuilder; metadata);
