Got error when trying to Fernet.Ecto.String.dump in test

Hello.

I'm trying to do this...

  defp encrypt_password(changeset) do
    case changeset do
      %Ecto.Changeset{valid?: true, changes: %{password: password}} ->
        put_change(changeset, :password_hash, Fernet.Ecto.String.dump(password))
      _ ->
        changeset
    end
  end

... in this test...

  test "creates and renders resource when data is valid", %{conn: conn} do
    conn = post conn, user_path(conn, :create), user: @valid_attrs
    body = json_response(conn, 201)
    |> IO.inspect
    assert body["data"]["id"]
    assert body["data"]["email"]
    assert body["data"]["password"]
    assert body["data"]["password_hash"]
    assert Repo.get_by(User, email: "[email protected]")
  end

... and got this:

1) test creates and renders resource when data is valid (Api.UserControllerTest)
   test/controllers/user_controller_test.exs:32

When I used the command in iex, it works ok:

iex(15)> Fernet.Ecto.String.dump("teste")
{:ok,
 "gAAAAABYzq-iDjQb5i1MYY8RXbFl9ZFfDQp2wyVWqAdPJIVKgMtFap-P8AtuvsNXqrcedp5CGaJjS9M2kBD60OPOR4l_tkDO8w=="}
iex(16)>

Can you help me to figure out why?

This is the structure in the DB:

  schema "users" do
    field :name, :string
    field :email, :string
    field :password, :string, virtual: true
    field :password_hash, Fernet.Ecto.String
