Вместо изменения входного фермента вставляет новую переменную в состояние моей TaskForm с неопределенным ключом и значением, которое я пытаюсь вставить.Мои результаты выглядят так:
Ожидаемое значение равно: {"description": "описание новой задачи", "id": "", "title": "new task"} Получено: {"description":"", "id": "", "title": "", "undefined": "new task"}
