Firebase 云功能不更新 Firestore 数据库中的数据

Question

So I'm writing a scheduled cloud function that is supposed to run every minute and update certain values in my Firestore database. I'm getting a success on the function and I don't see any errors, however, the database isn't updating. My project is made with flutter but I wrote the cloud function with node.js

enter image description here

This is my cloud function code.

 const functions = require('firebase-functions'); const admin = require('firebase-admin'); admin.initializeApp(functions.config().firebase); exports.myScheduledCloudFunction = functions.pubsub.schedule('* * * * *').timeZone('Asia/Kuala_Lumpur').onRun(async (context) => { admin.firestore().collection('users').get().then(function(querySnapshot) { querySnapshot.forEach(function(doc) { admin.firestore().collection('users').doc(doc.id).collection('habits').get().then(function(querySnapshot) { querySnapshot.forEach(function(habitDoc) { admin.firestore().collection('users').doc(doc.uid).collection('habits').doc(habitDoc.id).ref.update({ 'iscompleted': false, 'completedcount': 0 }) }) }) }) }) return null; });

I feel like it might be related to the rules but I'm not sure, for now my rules are default I haven't changed them. I hope someone can help

Thanks to @Doug Stevenson I've learned that I wasn't giving any time for the async functions to take its course. I have fixed my work and now it is working.

here's the fixed code:

 exports.myScheduledCloudFunction = functions.pubsub.schedule('* * * * *').timeZone('Asia/Kuala_Lumpur').onRun(async (context) => { const querySnapshot = await admin.firestore().collection('users').get(); querySnapshot.forEach(async (doc) => { const habitQuerySnapshot = await admin.firestore().collection('users').doc(doc.id).collection('habits').get(); habitQuerySnapshot.forEach(async (habitDoc) => { if (doc && doc.ref) { await habitDoc.ref.update({ 'iscompleted': false, 'completedcount': 0 }); } }); }); return null; });
