Firestore cloud functions summing subcollections values

I wish did fix the issue. You're not using promises correctly. You've got a lot of get() method call, each of which are asynchronous and return a promise, but you're never using them to case the entire function to wait for all the work to complete. Calling then() doesn't actually make your code wait - it just runs the next bit of code and returns another promise. Your final console.log is executing first because none of the work you kicked off ahead of it is complete yet.
Your code actually needs to be substantially different in order to work correctly, and you need to return a promise from the entire function that resolves only after all the work is complete.

This might help you It looks to me your return data is not same as the Interface modal. You only specified id and items fields in the interface, so it will be
code :
  const data = a.payload.data() as Container;
  const id = a.payload.id;
  let items=[];
  return {id:id, items: items};

hope this fix your issue according to firebase documentation:
code :
const client = require('firebase-tools');
await client.firestore
      .delete(collectionPath, {
        project: process.env.GCLOUD_PROJECT,
        recursive: true,
        yes: true

Cloud Firestore document read cost for subcollections?

fixed the issue. Will look into that further The location of a document has no bearing on the billing for its reads. It could be in a collection, or a subcollection, or a subcollection of a subcollection - it just doesn't matter. One document read always costs the same.
