Ash.TypedStruct doesn't support functions as default values?

Imagine a module like this:

defmodule ErrorContainer do
  @moduledoc false

  use Ash.TypedStruct

  typed_struct do
    field :marker, :uuid_v7 do
      allow_nil? false
      default &Ash.UUIDv7.generate/0
    end

    field :error, :term, allow_nil?: false
  end
end

Looking at the documentation and Ash.TypedStruct code, this should be supported.

In file ash/lib/ash/typed_struct.ex:92, it basically says in the typespec that using a function as a default value is supported: default: nil | term | (-> term),

But, when i try to create the object, I get an error:

iex(1)> ErrorContainer.new(error: :blibs)
{:error,
 %Ash.Error.Changes.InvalidAttribute{
   field: :marker,
   message: "is invalid",
   private_vars: nil,
   value: nil,
   has_value?: true,
   splode: nil,
   bread_crumbs: [],
   vars: [],
   path: [],
   stacktrace: #Splode.Stacktrace<>,
   class: :invalid
 }}

Is this a bug or an I doing something wrong?
