Elixir sending empty response on file upload

Hey, I am trying to upload an image to Elixir from a form and then to gcs using arc. The form returns an empty response from Elixir on submit. Whenever I upload an image, I get empty parameter from Elixir, please what can be the cause, why is Elixir receiving empty parameters. I am new to using Elixir and Arc, so I will like to confirm if my code is correct.

This is my mix.exs file

{:arc_gcs, "~> 0.1.0"},
{:arc_ecto, "~> 0.11.1"},
{:arc, "~> 0.11.0"}

Then my route for creating the post is
resources “/images”, ImagesController, except: [:new, :edit]

My Images Controller.create

def create(conn, images_params) do
  images_params["id"]})
    with {:ok, %Images{} = images} <- Images.create_images(images_params) do
      conn
      |> put_status(:created)
      |> put_resp_header("location", images_path(conn, :show, images))
      |> render("show.json", images: images)
    end
  end

This is my Images Model

 schema "image" do
       field :name, :string
       field :image, Myapp.Avatar.Type

       timestamps()
     end

     @doc false
     def changeset(images, attrs) do
       images
       |> cast(attrs, [:name])
       |> validate_required([:name])
       |> put_name
       |> cast_attachments(attrs, [:image])
       
       
     end

     def put_name(changeset) do
      case changeset do
        %Ecto.Changeset{
          valid?: true,
          changes: %{upload: %Plug.Upload{content_type: "image/" <> _, filename: name}}
        } ->
          put_change(changeset, :name, name)
        _ ->
          changeset
      end
     end

     def store(%Plug.Upload{} = upload, image) do
      Avatar.store({upload, image})
    end
  
    def url(image, version) do
      Avatar.url({image.name, image}, version)
    end

end

And finally my Arc Uploader

@versions [:original]

  def __storage, do: Arc.Storage.GCS

  def gcs_object_headers(:original, {file, _scope}) do
    [content_type: MIME.from_path(file.file_name)]
  end

  #To add a thumbnail version:
   @versions [:original, :thumb]

  # Override the bucket on a per definition basis:
  # def bucket do
  #   :custom_bucket_name
  # end

  # Whitelist file extensions:
  def validate({file, _}) do
    ~w(.jpg .jpeg .gif .png) |> Enum.member?(Path.extname(file.file_name))
  end

  def transform(:thumb, _file) do
    {:convert, "-thumbnail x#{@heights[:thumb]} -gravity center -format jpg"}
  end
  def transform(:show, _file) do
    {:convert, "-strip -resize x#{@heights[:show]} -gravity center -format png"}
  end

  def storage_dir(version, {_, image}) do
    "uploads/posts/images/#{image.id}/#{version}"
  end

  def filename(_version, {file, _}) do
    Path.rootname(file.file_name)
  end
end

This is expected to receive the uploaded image from the web and save it on Google Cloud Storage but the I'm still getting an empty parameter. I have been on this for days, any help at all would be really appreciated, please someone should look into this and tell me where I might be getting it wrong.

Thanks
