我只想从嵌套数组中获取第一个'firstPerson‘参数

def get_first_person(nested_array):
    for item in nested_array:
        if isinstance(item, list):
            result = get_first_person(item)
            if result is not None:
                return result
        elif isinstance(item, dict) and 'firstPerson' in item:
            return item['firstPerson']
    return None
