Storage `bucket.exists()` always returns false for firebase emulator

Empieza reproduciendo el problema con firebase emulators:start --only storage,functions usando la configuración indicada de firebase-admin@12.0.0 y firebase-tools@13.1.0. Rastrea getStorage().bucket() y bucket.exists() con el nombre del bucket predeterminado y compara después la solicitud y la respuesta del emulador con el estado esperado del bucket. Se considera terminado cuando bucket.exists() devuelve true para el bucket predeterminado correspondiente del emulador.

• For issues related to the code in this repository file a Github issue.
• If the issue pertains to Cloud Firestore, read the instructions in the "Firestore issue"
  template.
• For general technical questions, post a question on StackOverflow
  with the firebase tag.
• For general Firebase discussion, use the firebase-talk
  google group.
• For help troubleshooting your application that does not fall under one
  of the above categories, reach out to the personalized

[REQUIRED] Step 2: Describe your environment

• Operating System version: Ubuntu
• Firebase SDK version: firebase-admin@12.0.0 firebase-tools@13.1.0
• Firebase Product: storage
• Node.js version: 18.16.1
• NPM version: 9.5.1

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

Create basic project with storage and functions setup for emulation: (functions only used to call storage bucket methods)

// firebase.json
"emulators": {
    "functions": {
      "port": 5001
    },
    "storage": {
      "port": 9199
    },
    // ...rest of config

Run emulator with firebase emulators:start --only storage,functions
Verify storage bucket exists in emulator and the name is matched in firebase config showing storage_bucket as the default
Hit the firebase function to run the storage bucket code
Calling bucket.exists() from firebase function always returns false.

Expected outcome:
Calling bucket.exists() from firebase function return true when accessing the default bucket.

Relevant Code:

import { onRequest } from 'firebase-functions/v2/https';
import { getStorage } from 'firebase-admin/storage';

export const foo = onRequest(async (req, res) => {
  const storage = getStorage();
  console.log('APP STORAGE BUCKET:', storage.app.options.storageBucket);

  const bucket = storage.bucket();
  console.log('DEFAULT STORAGE BUCKET:', `name=${bucket.name}`, `id=${bucket.id}`);

  const exists = await bucket.exists();
  console.log('BUCKET EXISTS?:', exists);

  res.send(`BUCKET EXISTS?: ${exists}`);
});

Console output:

Emulator Storage: (name of bucket matches id in code)
