Custom predicates inside deep validation block

I have some custom predicates

I connect them in configure block

Then i try write this

optional(:items).value(:array?, min_size?: 1) do
          each do
            schema do
              required(:name).filled(:str?)
              required(:price).filled(:amount_format?, :amount_value?, :amount_currency?)
              required(:tax_type).filled(:str?, included_in?: Types::TaxTypes.values)
              optional(:quantity).filled(:int?)
            end
          end
        end

I have error -

`raise_unknown_predicate_error': +amount_format?+ is not a valid predicate name (ArgumentError)

I think, because i connect my predicates in configure block - when validation parse this rule - it don’t know about custom predicates

Question - how i can use custom predicates in deep validation block?
