我在使用Python将简单数据插入elasticsearch时犯了错误

Question

我刚刚接触了弹性搜索，在用python编写了一些简单的教程之后，插入数据时出现了一个错误。我的弹性搜索版本是6.4.0，Python版本是3.6macos版本是10.13.6 代码：

#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()})

错误：

PUT /my-index/test-type/1 [status:406 request:0.002s]
Traceback (most recent call last):
