Hello there!

I am trying to create a user. Creation fails from both the admin dashboard, as well as the /register route

This is the error message in the console:

** (Ash.Error.Unknown) Unknown Error

Context: resolving data on perform Memento.Accounts.User.register_with_password
* Context: resolving data on perform Memento.Accounts.User.register_with_password

** (RuntimeError) Missing JWT signing secret. Please see the documentation for `AshAuthentication.Jwt` for details

I have followed the authentication tutorial from the getting started guide.

This is my User resource:

defmodule Memento.Accounts.User do
  use Ash.Resource,
    data_layer: AshPostgres.DataLayer,
    extensions: [AshAuthentication]

  attributes do
    uuid_primary_key :id
    attribute :email, :ci_string, allow_nil?: false
    attribute :hashed_password, :string, allow_nil?: false, sensitive?: true
  end

  authentication do
    api Memento.Accounts

    strategies do
      password :password do
        identity_field :email
        sign_in_tokens_enabled? true
      end
    end

    tokens do
      enabled? true
      token_resource Memento.Accounts.Token

      signing_secret fn _, _ ->
        Application.fetch_env(:my_app, :token_signing_secret)
      end
    end
  end

  postgres do
    table "users"
    repo Memento.Repo
  end

  identities do
    identity :unique_email, [:email]
  end


end

I appreciate any guidance you can provide to solve this one.
