Using elcloud_s3 to upload to files to S3 i - erlang

Question

I am trying to use the erlang module erlcloud_s3 to upload a file to S3. For some reason that I have not been able to work out it does not work. I have included my code (with keys removed of course) and the response that I get when I try to run this. Can someone tell me what I am missing (or if there is a better AWS package for Erlang that actually has some docs or examples?)
-module(compose).
-define('ACCESS_KEY', "********************").
-define('SECRET_ACCESS_KEY', "****************************************").
-define('BUCKET', "zacharykessin").
-export([upload/2, upload_file/2]).
upload_file(Key, Path) ->
R = file:read_file(Path),
{ok, Binary} = R,
upload(Key, Binary).
upload(Key, Value) ->
A = erlcloud_ec2:configure(?ACCESS_KEY, ?SECRET_ACCESS_KEY),
error_logger:info_msg("~p:~p Settng up AWS ~p to S3 ~n",
[?MODULE, ?LINE, A]),
R = erlcloud_s3:put_object(?BUCKET, Key, Value, [], [{"Content-type", "image/jpeg"}]),
error_logger:info_msg("~p:~p Uploaded File ~p to S3 ~n",
[?MODULE, ?LINE, R]),
{ok, R}.

Make sure to run
inets:start()
somewhere before running your code.
The error you are getting means that there is no such process (noproc) registered as httpc_manager, which is a part of inets library application.
