Your firestore query isn't returning anything; probably because either the document/collection doesn't exist.
Right off the bat, it stands out that your "notification_id" is queried as string, rather than the const you set earlier. It's kind of a gamble, but changing line 10 to this may help:
return admin.firestore().collection("ServiceProviders").doc(user_id).collection("Notifications").doc(notification_id).get().then(querySnapshot => {
