Reactor not recognizing inputs transform?

Hi there, I have the following Reactor code:

defmodule CreateNewAccount do
  use Reactor, extensions: [Ash.Reactor]
  alias Accounts.Account

  ash do
    default_domain Accounts
  end

  input(:email)
  input(:email_is_verified?)

  create :account, Account do
    inputs %{
      email: input(:email),
      email_is_verified?: input(:email_is_verified?)
    } do
      transform(fn input ->
        input
        |> Map.drop([:email_is_verified?])
        |> Map.put(
          :email_verified_at,
          if input[:email_is_verified] do
            nil
          else
            DateTime.now()
          end
        )
      end)
    end
  end
end

But I’m getting the following error

Compiling 2 files (.ex)

== Compilation error in file lib/create_new_account.ex ==
** (Spark.Error.DslError) [CreateNewAccount]
reactor -> create -> account:
  The create step `:account refers to an input named `email_is_verified?` which doesn't exist.

Did you mean `updated_at`, `created_at`, `id`, `email` or `email_verified_at`?

Looks like the DSL isn’t recognizing that I’m transforming the input. Is this a bug or am I just doing something incorrect?

Thank you!
