Question

因此，在Elixir / Phoenix应用程序的iex远程控制台外壳程序中（我的操作仅在远程控制台外壳程序中），我正在执行Logger.info "debug message"之类的操作，它具有第三方记录服务。调用Logger＃info / 1后，控制台中始终出现如下错误：

    iex server-xxx 3> :gen_event handler Timber.LoggerBackends.HTTP installed in Logger terminating
** (exit) an exception was raised:
    ** (ArgumentError) argument error
        (stdlib) :ets.lookup_element(:hackney_config, :mod_metrics, 2)
        (hackney) /root/project/deps/hackney/src/hackney_metrics.erl:27: :hackney_metrics.get_engine/0
        (hackney) /root/project/deps/hackney/src/hackney_connect.erl:78: :hackney_connect.create_connection/5
        (hackney) /root/project/deps/hackney/src/hackney_connect.erl:47: :hackney_connect.connect/5
        (hackney) /root/project/deps/hackney/src/hackney.erl:330: :hackney.request/5

        (timber) lib/timber/logger_backends/http.ex:211: Timber.LoggerBackends.HTTP.handle_info/2
        (stdlib) gen_event.erl:577: :gen_event.server_update/4

我将其追溯到对hackney（这是Erlang，我不太了解）的请求：

 :hackney.request(method, url, req_headers, body, req_opts)

结束

以下是我处理过的带有经过身份验证的auth令牌（从远程调试会话中剔除）的参数：

如何识别导致问题的“错误论点”？我是Erlang的新手。
