第一个任务正常，但之后每个任务都会出现此错误 -

我正在使用的任务如下：
@celery.task(base=RequestContextTask, name='export.event', bind=True)
def export_event_task(self, email, event_id, settings):
event = safe_query(db, Event, 'id', event_id, 'event_id')
user = db.session.query(User).filter_by(email=email).first()
try:
logging.info('Exporting started')
path = event_export_task_base(event_id, settings)
# task_id = self.request.id.__str__() # str(async result)
download_url = path
result = {
'download_url': download_url
}
logging.info('Exporting done.. sending email')
send_export_mail(email=email, event_name=event.name, download_url=download_url)
send_notif_after_export(user=user, event_name=event.name, download_url=download_url)
except Exception as e:
print(traceback.format_exc())
result = {'__error': True, 'result': str(e)}
logging.info('Error in exporting.. sending email')

我不知道我在这里失踪了什么。我尝试了Github回购中提到的所有解决方案但没有工作。
