bun.sh grpc-js :: undefined is not an object (evaluating 'error.stack.split') :: what am I missing?

### [REQUIRED] Step 2: Describe your environment

* Operating System version: macOS 13.5.2 (22G91)
* Firebase SDK version: 11.10.1
* Firebase Product: firestore
* Node.js version: 18.17.1
* NPM version: 8.19.2

### [REQUIRED] Step 3: Describe the problem

I'm testing out [bun](https://bun.sh) and I can't do a basic get() on a collection. What am I missing?

#### Steps to reproduce:

index.ts
```
require('dotenv').config()

import { initializeApp } from 'firebase-admin/app'
initializeApp()
import { getFirestore } from 'firebase-admin/firestore'
export const db = getFirestore()
db.collection('category').get()
```

Run

```
bun index.ts

[0.05ms] ".env"

30 | function isFunction(arg) {
31 | return typeof arg === 'function';
32 | }
33 | function getErrorStackString(error) {
34 | return error.stack.split('\n').slice(1).join('\n');
