when i use depprase for denpendency analysis with chinese in client, the results:root:3;rootnode:2?it is correct? can rootnode be a numer over 0?

this is my coding： f``` rom stanza.server import CoreNLPClient text = " 天河潭位于贵州省贵阳市花溪区石板镇，是以典型喀斯特自然风光为主、历史名人隐士文化为辅的风景名胜区，距贵阳市中心24公里，距花溪13公里，总面积为15平方公里。" with CoreNLPClient( annotators=['tokenize','ssplit','pos','lemma','ner', 'parse', 'depparse','coref'], timeout=30000, memory='6G', properties="chinese", endpoint="http://localhost:9008", outputFormat='json') as client: ann = client.annotate(text) for sentence in ann.sentence: print(sentence.basicDependencies)



_**this is output：**_

root: 3
rootNode: 2

Now，you can see the root：3，rootnode：2. Maybe the reason is i input a complex long Chinese sentence to cilent?

when i use depprase for denpendency analysis with chinese in client, the results:root:3;rootnode:2?it is correct? can rootnode be a numer over 0? #1379
