Перестал работать скрипт в 11.1.1.11

Добрый день,

После обновления квика до версии 11.1.1.11 перестал работать скрипт отрисовывающий горизонтальные уровни (lineFractals), который работал у меня с незапамятных времён.
Пожалуйста, подскажите как поправить индикатор. Писал его не я и сам не смогу разобраться.

Вид индикатора: https://ibb.co/GCPfV3D



Выдаваемая ошибка: "C:\QUIK_VTB\LuaIndicators\lineFractals.lua:114: attempt to call a nil value (global 'unpack')"

Текст индикатора:
