For recently uploads:

1. Delete line 3 <====> const firebaseConfig = require('./src/config/firebase.js')

2. Change line 25 <====> await firestoreService.initializeApp(serviceAccount, firebaseConfig.databaseURL)
   to <====> const firestore = await firestoreService.initializeFirebaseApp(serviceAccount)

3. Change line 28 <====> await firestoreService.restore(tempFileName))
   to <====> await firestoreService.restore(firestore, tempFileName)

This works...
