我正在使用 clojure rethinkdb 库https://github.com/apa512/clj-rethinkdb - 这是我的连接片段：
(ns rethink.core
(:require
[environ.core]
[cheshire.core :as json]
[org.httpkit.client :as http]
[rethinkdb.query :as r]))
(defn rethink-connect
[]
(r/connect :host (environ.core/env :rethinkdb-host)
:port (environ.core/env :rethinkdb-port)
:db (environ.core/env :rethinkdb-db)
:auth-key (environ.core/env :rethinkdb-auth)))
(defn record-event!
[event collection]
(let [r (with-open [conn (rethink-connect)]
(-> (r/table collection)
(r/insert [event])
(r/run conn)))]))
但我不断收到错误：

我正在从我的 compose.io rethinkdb 实例中获取主机“aws-us-xxx-1-portal.xxx.xxxx.com”、端口“15731”、db“dev”和 auth-key。auth-key 是从 compose.io 接口提供的身份验证凭据中获取的管理员密码。不知道发生了什么。
