Я пытаюсь заставить json отображаться в карточках или списке после поиска. Поисковая часть, кажется, работает, так как я вижу вызов API с текстом, написанным в окне поиска в консоли. но ничего не отображается, и я получаю эту ошибку TypeError: Невозможно прочитать свойство 'data' из undefined. Я не думаю, что получаю правильный путь json.
