How to use firebase admin SDK in local Node.js scripts?

Question

I'm trying to use the firebase admin sdk in a local node.js script file (outside of firebase-functions) in order to preform some auth and firestore operations.

But I get this error:

{"severity":"WARNING","message":"Warning, FIREBASE_CONFIG and GCLOUD_PROJECT environment variables are missing. Initializing firebase-admin will fail"}

Error: Failed to determine project ID: Error while making request: getaddrinfo ENOTFOUND metadata.google.internal. Error code: ENOTFOUND

Admin SDK initialization:

const admin = await import('firebase-admin');
const serviceKey = require('path/to/serviceKey.json');
admin.initializeApp({
    credential: admin.credential.cert(serviceKey),
    databaseURL: 'https://{project}.firebaseio.com',
});

All the questions I've found on this error are regarding running firebase-functions locally, but I'm not trying to use firebase-functions, I'm only trying to use admin.auth and admin.firestore locally.

Am I missing something here?

It works with the codes below based on this documentation:

const admin = require('firebase-admin');
const serviceKey = require('./path/to/serviceKey.json');
admin.initializeApp({
    credential: admin.credential.cert(serviceKey),
    databaseURL: 'https://{project}.firebaseio.com'
});

I also saw this question, creating new Google Cloud project from current Firebase project and upgrading Firebase project plan to Blaze Plan fixed the problem.
