Issue deploying Firebase functions - Cannot read property 'firebase-admin' of undefined

Question

I'm encountering an issue while deploying Firebase functions, and I would appreciate any assistance in resolving it. The deployment itself seems fine, but I'm getting the following error:

Cannot read property 'firebase-admin' of undefined npm ERR! A complete log of this run can be found in:

Dependencies:

• "firebase-admin": "^11.8.0"
• "firebase-functions": "^4.3.1"

Local Environment:

• Node version: v20

Function Code:

import * as admin from "firebase-admin";
import * as functions from 'firebase-functions';
const serviceAccount = require('./mooland-999ad-e0753014493a.json');

const app: admin.app.App = admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
});

exports.listUsers = functions.https.onRequest(async (req, res) => {
  try {
    const listUsersResult = await app.auth().listUsers();
    const users = listUsersResult.users.map((userRecord) => ({
      id: userRecord.uid,
      email: userRecord.email,
      name: userRecord.displayName,
      // Add more user information as needed
    }));

    res.json(users);
  } catch (error) {
    console.error('Error listing users:', error);
    res.status(500).send('Internal Server Error');
  }
});

Error log:

Any help is appreciated.

I solved the issue by adding "type": "module", to package.json and changing the file name index.js to index.cjs
