Я допустил ошибки, когда использовал Python для вставки простых данных вasticsearch

Question

Я только что коснулся упругого поиска, и после нескольких простых уроков по python произошла ошибка при вставке данных. Моя упругая поисковая версия была 6.4.0, а моя версия Python была 3.6, версия macOS была 10.13.6 код:

#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()})

Ошибка:

PUT /my-index/test-type/1 [status:406 request:0.002s]
