Having в msproducts

Добрый день. Не получается с помощью msproducts и msproductremains вывести товары которые остались в одном экземпляре. На странице дополнения есть пример вывода товаров, которые есть в наличии:

[[!msProducts?
  &leftJoin=`{"Remains":{"class":"msprRemains","on":"msProduct.id = Remains.product_id AND Remains.remains > 0"}}`
  &groupby=`msProduct.id`
  &select=`{"msProduct":"*","Remains":"SUM(Remains.remains) as remains"}`
  &where=`{"Remains.remains:>":"0"}`
]]

Анализ лога итогового запроса показал, что вывести аналогичным образом продукты с суммарным остатком = 1 не получится и нужно использовать having.

Корректный код, на мой взгляд, должен выглядеть вот так:

[[!msProducts?
  &parents=`10`
  &limit=`3`
  &leftJoin=`{"Remains":{"class":"msprRemains","on":"msProduct.id = Remains.product_id AND Remains.remains > 0"}}`
  &groupby=`msProduct.id`
  &select=`{"msProduct":"*","Remains":"SUM(Remains.remains) as rem"}`
  &having=`Remains.rem=1`
  &tpl=`productsRow`
]]

Но он выдает 500-ую ошибку:

Срок поддержки msproductremains закончился. Подскажите, в чём проблема и как добиться желаемого?
Ниже лог запроса без having
