Ash Authentication password strategy token error when following Getting Started Guide

Following the Ash Authentication Phoenix Getting Started Guide, I get the following error message when trying to save/compile the user.ex resource:

    ** (Spark.Error.DslError) [nil]
 authentication -> tokens -> enabled?:
  The `:password` authentication strategy requires tokens be enabled.

To fix this error you can either:
  1. disable the `:password` strategy, or
  2. enable tokens.

The authentication section of the user.ex resource is as specified in the guide:

  authentication do
    strategies do
      password :password do
        identity_field :email
      end
    end
    ...
 end

I tried adding “sign_in_tokens_enabled? true” in the password section of authentication. However, they did not work either.

How would I enable the tokens to be able to use the password authentication strategy? Docs say tokens are enabled by default?

I expect I am overlooking something obvious.

Any help would be appreciated. Thanks to everyone for the great work on Ash 3.0.
