firebase-admin-node: 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 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
