`initFirebaseRest` doesn't work with edge runtime on NextJS

[ahsankhan26]

I just came across this package and tried setting up on my repo. I am using NextJS 14 and edge runtime.
I am deploying the app on cloudflare pages so all routes have to be on edge.
Is there any workaround for this?

// app/login/page.tsx
export const runtime = 'edge';

// firebase.ts
import { initFirebaseRest } from 'firebase-admin-rest';

export const getFirebaseAdmin = async () => {
  const db = await initFirebaseRest({
    serviceAccount,
    databaseId: '(default)', 
  }).firestore();
  return db;
};

CallinggetFirebaseAdmin in a server action results in the following error.

ERROR
