Phoenix/Elixir - Invalid Parameter error with Arc Ecto cast_attachments - amazon-s3

Question

I am trying to make an image upload function with Phoenix/elixir, and I am getting an error on the create action with my console giving me the following error message:
[debug] Processing by Callme.DoctorController.create/2

Here is the the create action:
def create(conn, %{"doctor" => doctor_params}) do
changeset = Doctor.changeset(%Doctor{}, doctor_params)
case Repo.insert(changeset) do
{:ok, _doctor} ->
conn
|> put_flash(:info, "Doctor created successfully.")
|> redirect(to: doctor_path(conn, :index))
{:error, changeset} ->
render(conn, "new.html", changeset: changeset)
end
And here is my doctor.ex file:
defmodule Callme.Doctor do
use Callme.Web, :model
use Arc.Ecto.Model
schema "doctors" do
field :name, :string
field :hiddeninfo, :string
field :bio, :string
field :specialty, :string
field :picture, :string
field :avatar, Callme.Avatar.Type
has_many :services, Callme.Service
timestamps
end
#required_fields ~w(name hiddeninfo bio specialty picture )
#optional_fields ~w()
#required_file_fields ~w()
#optional_file_fields ~w(avatar)
#doc """
Creates a changeset based on the `model` and `params`.
If no params are provided, an invalid changeset is returned
with no validation performed.
"""
def changeset(model, params \\ :empty) do
model
|> cast(params, #required_fields, #optional_fields)
|> cast_attachments(params, #required_file_fields, #optional_file_fields)
end
end
Here is the Avatar.ex file:
defmodule Callme.Avatar do
use Arc.Definition
use Arc.Ecto.Definition
# Include ecto support (requires package arc_ecto installed):
# use Arc.Ecto.Definition
#versions [:original, :thumb]
#extension_whitelist ~w(.jpg .jpeg .gif .png)
def acl(:thumb, _), do: :public_read
def validate({file, _}) do
file_extension = file.file_name |> Path.extname |> String.downcase
Enum.member?(#extension_whitelist, file_extension)
end
def transform(:thumb, _) do
{ :noaction }
end
def filename(version, _) do
version
end
def storage_dir(_, {file, user}) do
"uploads/avatars/#{user.id}"
end
def default_url(:thumb) do

And also, here is a link to the github repository because I can't think of any other files that might have errors on them.
I hope we can figure this out. This has been literally an entire week now of trying to figure what is wrong with this thing and I feel like I am taking crazy pills.
