Я работаю над фрагментом кода в Nim, который извлекает объект JSON из API Shodan. Вот полная строка JSON от Shodan:

Весь код, работающий с интерфейсом API, работает нормально, но у меня возникают проблемы при разборе результирующих объектов JSON. Когда объекты просты, синтаксический анализатор Нима работает нормально, но когда я попытался проанализировать вышеупомянутый JSON, я получаю ошибку. Код Nim, используемый для анализа JSON:
let jsonRsp = parseJson(rspJson)
И ошибка, создаваемая компилятором:

Error: unhandled exception: Parsed integer outside of valid range [ValueError]
Я получаю то, что говорит ошибка, что один изцелые числа слишком длинные для парсера. Поскольку я не могу изменить данные (это то, что выкладывает API), я смотрю, есть ли у кого-нибудь стратегии для анализа таких JSON-данных в Nim. Помимо жалобы компилятора, каждый другой валидатор JSON показывает строку как действительный JSON.
