При обращении к doc в скрипте map_script агрегации, я получаю исключение нулевого указателя.
Для
{
"init_script":{
"source":"params._agg['transactions'] = [];"
},
"map_script":{
"source":"Debug.explain(params)" <----------------
},
...
}
Я получаю
{
...,
"painless_class":"java.util.HashMap",
"to_string":"{doc=org.elasticsearch.search.lookup.LeafDocLookup@133b9d24, _source=org.elasticsearch.search.lookup.SourceLookup@7b812d13, _doc=org.elasticsearch.search.lookup.LeafDocLookup@133b9d24, _fields=org.elasticsearch.search.lookup.LeafFieldsLookup@6149f5f3, _agg={transactions=[]}}",
"java_class":"java.util.HashMap",
...
}
Здесь Debug.explain(params._agg) доступен без проблем, как и Debug.explain(params.containsKey('doc')), который возвращает
{
...,
"painless_class":"java.lang.Boolean",
"to_string":"true",
"java_class":"java.lang.Boolean",
...
}
Если, однако, я получаю доступ к
params.docparams['_doc']doc_doc- или любой их вариант
Я продолжаю получать
{
...,
"caused_by":{
"type":"null_pointer_exception",
"reason":null,
"caused_by":{
"type":"null_pointer_exception",
"reason":null
}
},
...
}
Что происходит? И почему я вижу LeafDocLookup экземпляров, к которым нельзя получить доступ и которые выглядят не строковыми / toString () - ed?
