Всем привет. Связался с API Head Hunter для вывода данных по вакансиям. Когда на вход подаётся два значения, например (вакансии по Python, Java) скрипт отрабатывает, но если на вход будет подано больше двух значений в трейсбеке:
TypeError: 'NoneType' object is not subscriptable
Подскажите в чем ошибка?
