TypeError: Cannot read properties of undefined (reading 'user')
[REQUIRED] Environment info firebase-tools: 14.4.0
Platform: macOS
[REQUIRED] Test case functions/package.json content:
JSON
{ "name": "functions", "description": "Cloud Functions for Firebase", "scripts": { "serve": "firebase emulators:start --only functions", "shell": "firebase functions:shell", "lint": "eslint .", "start": "npm run shell", "deploy": "firebase deploy --only functions", "logs": "firebase functions:log" }, "engines": { "node": "22" }, "main": "index.js", "type": "module", "dependencies": { "eslint": "^9.28.0", "express": "^5.1.0", "firebase-admin": "^13.4.0", "firebase-functions": "^6.3.2", "stripe": "^18.2.1" }, "devDependencies": { "eslint-config-google": "^0.14.0", "firebase-functions-test": "^3.1.0" }, "private": true } functions/index.js content (minimal test case):
JavaScript
import * as functions from 'firebase-functions'; import { initializeApp } from 'firebase-admin/app'; import * as admin from 'firebase-admin'; // Keep this for admin.firestore() etc.
initializeApp();
export const testAuthTriggerMinimal = functions.auth.user().onCreate((user) => { console.log('New user created in new project:', user.uid); return null; // Or return admin.firestore().collection('users').doc(user.uid).set({...}); if you want to test that fully }); Node.js Version: v22.14.0 Node.js Executable Path: /usr/local/bin/node
[REQUIRED] Steps to reproduce Create a brand new Firebase project in the Firebase Console (e.g., my-auth-test-project-250617). Initialize a new Firebase project locally in an empty directory: mkdir ~/temp-firebase-auth-test && cd ~/temp-firebase-auth-test Run firebase init functions and link to the new Firebase project created in step 1. Select JavaScript, decline ESLint, and allow npm install to run. Navigate into the functions directory: cd functions Update the functions/package.json content as provided in the "Test case" section above (ensure engines.node is "22", "type": "module" is added, and firebase-admin and firebase-functions are updated to ^13.4.0 and ^6.3.2 respectively, along with other dependencies if needed). Run npm install in the functions directory to install updated dependencies. Replace the content of functions/index.js with the minimal test case provided in the "Test case" section above. Navigate back to the project root: cd .. Attempt to deploy the function: firebase deploy --only functions:testAuthTriggerMinimal --debug [REQUIRED] Expected behavior The testAuthTriggerMinimal Cloud Function should deploy successfully to the Firebase project.
[REQUIRED] Actual behavior The deployment fails during the "Loading and analyzing source code" phase with a TypeError: Cannot read properties of undefined (reading 'user') error.

Hey @EpicEric3ric, thanks for the detailed report! Looking at the code you provided, it seems like you're trying to use v1 functions instead of v2 functions. For context starting firebase-functions v6.0.0 the default entry point of the package was changed to v2 instead of v1.
Try updating you code to explicitly import from firebase-functions/v1
import * as functions from 'firebase-functions/v1'; // explicitly imports v1 functions
import { initializeApp } from 'firebase-admin/app';
import * as admin from 'firebase-admin'; // Keep this for admin.firestore() etc.
initializeApp();
export const testAuthTriggerMinimal = functions.auth.user().onCreate((user) => {
console.log('New user created in new project:', user.uid);
return null; // Or return admin.firestore().collection('users').doc(user.uid).set({...}); if you want to test that fully
});
Do you still see any errors after updating the code?
edit:
I noticed you were using node 22 as your engine in package.json. You might encounter an error when deploying since nodejs22 is not a valid runtime for 1st gen functions, see this issue https://github.com/firebase/firebase-tools/issues/8704. If you do encounter an INVALID_RUNTIME error when deploying, try changing your engine to use node 20.
...
"engines": {
"node": "20"
},
...
Will do and thanks for the follow up! I'll work on it when I can.
Sincerely,
Eric
