Firebase Cloud Functions: Error while deploying function

Question

I'm deploying the following function to firebase:

const functions = require("firebase-functions");
const firebase = require("firebase-admin");
firebase.initializeApp()
var firestore = firebase.firestore()

exports.resetCreditsForFreeUsers = functions.pubsub
    .schedule('* * * * *')
    .onRun(async (context) => {
        const users = firestore.collection('tests')
        const user = await users.get()
        user.forEach(snapshot => {
            snapshot.ref.update({ balance: 10 })
        })
        return null;
    })

with the command firebase deploy --only functions and the output is:

i  deploying functions
Running command: npm --prefix "$RESOURCE_DIR" run lint
npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.

I can't figure out how to solve this error.

EDIT WITH Dharmaraj answer I tried your answer with Promise.

Error:

EDIT changing update() with set()

Error: Failed to list functions for betty-sport

Answer 1

The .update() returns a Promise so you should wait for it to resolve. Try refactoring the code as shown below:

exports.resetCreditsForFreeUsers = functions.pubsub
  .schedule('* * * * *')
  .onRun(async (context) => {
    const users = firestore.collection('tests')
    const user = await users.get()

    const promises = user.docs.map(d => d.ref.update({ balance: 10 }));

    await Promise.all(promises);

    return null;
  })

Alternatively, you can also use a batched write to update up to 500 documents at once instead of individually updating them.
