Unable to start the bot

[rekyuu]

Hiya, I'm pretty sure I'm just screwed up somewhere but I wanted a second pair of eyes to see why this isn't starting. I don't have anything crazy in the bot, just having it start with a supervisor and then have it parse events.

My repo is at https://github.com/KumaKaiNi/discord-kuma. The error I'm getting is as follows:

== Compilation error on file lib/discord_kuma/bot.ex ==

The code I'm using to start the bot:

defmodule DiscordKuma.Bot do
  {:ok, _bot_client} = DiscordEx.Client.start_link(%{
    token: Application.get_env(:discord_kuma, :discord_token),
    handler: DiscordKuma.Module
  })
end

Thanks for the help.

I also tried working backwards with the Rest API and got

iex(6)> {:ok, rest} = DiscordEx.RestClient.start_link(%{token: token})
{:ok, #PID<0.272.0>}
iex(7)> DiscordEx.RestClient.Resources.User.current(rest)
%{"code" => 0, "message" => "401: Unauthorized"}

Looking through the most recent commit it seems there is code that was not installed with Hex, likely a version bump and Hex update issue. Regardless I tried the fix of adding Bot to the beginning of token and I still get the same error as I did in the first comment. It does however work for the Rest client when I do the new token with the same code as I did in post 2. If I remove the following and start iex and run Client.start_link manually it also works, so it seems to be an issue with genserver and hackney while it's compiling. While running it manually I sent my bot a message and got the following:

Dunno how I managed to completely destroy this library but I hope I've given enough info to see what's going on. lol

Got it working, turns out HTTPoison wasn't starting in application for whatever reason so I manually invoked it:

defmodule DiscordKuma do
  require Logger

  def start(_type, _args) do
    Logger.debug "Starting HTTPoison..."
    HTTPoison.start

    Logger.debug "Starting bot..."
    DiscordEx.Client.start_link(%{
      token: Application.get_env(:discord_kuma, :discord_token),
      handler: DiscordKuma.Module
    })
  end
end

Thanks!
