Firebase Storage getDownloadURL doesn't finish running

[ulbqb]

[REQUIRED] Describe your environment

• Operating System version: MacOS 11.6
• Browser version: No Browser
• Firebase SDK version: 9.1.3
• Firebase Product:Storage
• Nodejs version: 14.18.0

[REQUIRED] Describe the problem

When I try to get the Storage DownloadURL with Nodejs, the getDownloadURL function works fine, but Nodejs doesn't finish running.
firebase-js-sdk should support the Nodejs environment.
https://firebase.google.com/docs/web/environments-js-sdk

Steps to reproduce:

Run the following code in Nodejs (14.18.0).
In my environment, Download URL is output normally, but Nodejs execution does not finish.

Relevant Code:

'use strict'
const { initializeApp } = require('firebase/app')
const { getStorage, ref, getDownloadURL } = require('firebase/storage')

initializeApp(
  {
    apiKey: '',
    authDomain: '',
    projectId: '',
    storageBucket: '',
    messagingSenderId: '',
    appId: '',
    measurementId: ''
  }
)

!(async () => {
  const storage = getStorage()
  const pathReference = ref(storage, 'sample.txt')
  const url = await getDownloadURL(pathReference)
  console.log(url)
})()

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @ulbqb, thanks for reporting this behavior. I tried following the steps you've provided to replicate the issue, however, I was able to get the download url. If I can replicate the issue, I can have a better look into it. Please share a minimal, but complete sample of a project that I can run locally.

Hi @jbalidiong, thanks for reply. I upload minimal project to https://github.com/ulbqb/firebase-js-sdk-issue-5628.
Result in my environment:

$ time npm run start

> firebase-js-sdk-issue-5628@1.0.0 start /Users/ulbqb/firebase-js-sdk-issue-5628
> node index.js

real    2m0.716s
user    0m0.581s
sys     0m0.142s
$ 

The problem is that the Download URL is printed correctly immediately, but the process doesn't finish until I wait a few minutes after it's printed.

Thanks for the minimal repro. I was able to reproduce the behavior now. Let me check what we can do for this issue or bring someone here that can provide more context about it. I’ll update this thread if I have any information to share.

Does the issue still persist even you delete the Firebase app? This should stop all background activity.

I tried deleteApp function but it didn't solve the problem.

Hello !

I see the same problem with the functions of storage library called with mocha to test the security rules (@firebase/rules-unit-testing).

I tested the function listAll and deleteObject. Same problem with both.
I have to wait around 2 minutes after the test finishes to see the process finish.
