Django djstripe客户订阅删除webhook事件无法正常工作

我已将djstripe webhook订阅删除webhook配置为以取消状态保存订阅

from djstripe import webhooks
import djstripe.model

@webhooks.handler("customer.subscription.deleted")
def subscription_deletion_handler(event, **kwargs):
    data = event.data.get("object", {})
    djstripe_subs_status = data.get('status')
    djstripe_subs_id = data.get('id')

    djstripe_subscription = djstripe.models.Subscription.objects.get(id=djstripe_subs_id)
    djstripe_subscription.status = djstripe_subs_status
    djstripe_subscription.save() 

但在获取订阅对象时，它会抛出

djstripe.models.billing.subscription.DoesNotExist

异常并自动从数据库中删除对象。请纠正我，让我知道，如果有任何问题，在上述代码
