我正在尝试运行一个项目，但每次我尝试加载特定页面时，它都会抛出以下错误堆栈：

Traceback (most recent call last):

而且我无法弄清楚究竟什么是格式错误的 IP 地址以及此错误背后的原因。

以下是 get_current_timezone() 函数：

def get_current_timezone():
    match = geolite2.lookup(get_real_ip(True) or '127.0.0.1')
    if match is not None:
        return match.timezone
    else:
        return 'UTC'

以下是 get_real_ip() 方法：

def get_real_ip(local_correct=False):
    try:
        if 'X-Forwarded-For' in request.headers:
            ip = request.headers.getlist("X-Forwarded-For")[0].rpartition(' ')[-1]
        else:
            ip = request.remote_addr or None

        if local_correct and (ip == '127.0.0.1' or ip == '0.0.0.0'):
            ip = urlopen('http://ip.42.pl/raw').read()  # On local test environments
    except:
        ip = None

    return ip

以下是创建此问题的创建事件视图部分：

@events.route('/create/', defaults={'step': ''})
@events.route('/create/<step>')
def create_view(step):
    if step != '':
        return redirect(url_for('.create_view', step=''))

    hash = get_random_hash()
    if CallForPaper.query.filter_by(hash=hash).all():
        hash = get_random_hash()

    current_timezone = get_current_timezone()

    return render_template(
        'gentelella/admin/event/wizard/wizard.html',
        current_date=datetime.datetime.now(),
        event_types=DataGetter.get_event_types(),
        event_licences=DataGetter.get_event_licences(),
        event_topics=DataGetter.get_event_topics(),
        event_sub_topics=DataGetter.get_event_subtopics(),
        timezones=DataGetter.get_all_timezones(),
        cfs_hash=hash,
        current_timezone=current_timezone,
        payment_countries=DataGetter.get_payment_countries(),
        payment_currencies=DataGetter.get_payment_currencies(),
        included_settings=get_module_settings())
