我在使用Python将简单数据插入elasticsearch时犯了错误

我刚刚接触了弹性搜索，在一些简单的python教程之后，插入数据时出错。我的弹性搜索版本是6.4.0，Python版本是3.6，macOS版本是10.13.6 代码：

错误：

这是一个声明，不是一个问题。您需要什么帮助？问题在哪里？如何解决？

#from datetime import datetime
from elasticsearch import Elasticsearch

es = Elasticsearch()

es.indices.create(index='my-index', ignore=400)

es.index(index="my-index", doc_type="test-type", id=1, body={"any":"data01", "timestamp": datetime.now()})
