How to use escalus component from elixir?

[izigibran]

I am trying to connect escalus_component to mongooseim locally from elixir

I call this:

Interactive Elixir (1.6.4) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> conarg = [{:host, "localhost"}, {:password, "secret"},{:port, 8888},{:component,"mongooseim@localhost"}]
[
  host: "localhost",
  password: "secret",
  port: 8888,
  component: "mongooseim@localhost"
]
iex(2)> :escalus_component.start_link(:escalus_component, conarg, [])  
** (EXIT from #PID<0.282.0>) shell process exited with reason: an exception was raised:
    ** (FunctionClauseError) no function clause matching in :escalus_component.init/1
        /Users/gibranrodriguez/everdays/full-stack-react-phoenix/chat_app/deps/escalus/src/escalus_component.erl:103: :escalus_component.init([])
        /Users/gibranrodriguez/everdays/full-stack-react-phoenix/chat_app/deps/escalus/src/escalus_component.erl:109: :escalus_component.init/1

        (stdlib) proc_lib.erl:247: :proc_lib.init_p_do_apply/3

On Mongooseim node this happens:

I guess I would like some help on an example how to connect escalus_component to mongooseim either from elixir or erlang
