问题

遇到了相同的问题，除非我将客户端降级到7.5.1。有没有更新导致此问题的原因？使用python客户端elasticsearch dsl=6和elasticsearch=6A时出现了相同的问题？问题是，您正在使用代理访问aws elastic cluster？

es = elasticsearch.Elasticsearch(
    hosts=[
        ES_ENDPOINT
    ],
    http_auth=awsauth,
    use_ssl=True,
    verify_certs=True,
    ssl_show_warn=True,
    connection_class=elasticsearch.RequestsHttpConnection,
    http_compress = True <--- This line causes the error.
)
