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

首先，使用报告中的 firebase-admin@12.0.0 和 firebase-tools@13.1.0 设置，通过 firebase emulators:start --only storage,functions 重现该问题。使用默认 bucket 名称跟踪 getStorage().bucket() 和 bucket.exists()，然后将 emulator 的请求和响应与预期的 bucket 状态进行比较。当 bucket.exists() 针对匹配的默认 emulator bucket 返回 true 时，即表示完成。

[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)
