GCP Cloud Functions with Firestore Trigger Not Invoking as Expected
I've been banging my head against this for hours. I'm working on a personal project and I've searched everywhere and can't find a clear answer... I'm stuck on something that should probably be simple... Currently developing a client application that integrates GCP Cloud Functions with Firestore to handle real-time data updates. Despite setting up the function correctly, it doesn't seem to trigger as intended when new documents are added to a specified Firestore collection. Here’s how I configured it: ```javascript const functions = require('firebase-functions'); const admin = require('firebase-admin'); admin.initializeApp(); exports.onDocumentCreate = functions.firestore.document('myCollection/{docId}') .onCreate((snap, context) => { const newValue = snap.data(); console.log('New Document Created:', newValue); return null; }); ``` The function is deployed correctly, and I verified that other functions are working without issues. However, the Firestore triggers don't seem to invoke this function when new documents are created. I’ve checked the Firestore rules and confirmed that write operations are permitted, yet the Cloud Functions logs show no invocation attempts. To troubleshoot, I: - Re-deployed the function several times, ensuring the latest code is live. - Reviewed the Firestore rules to confirm they allow the intended operations: ```json service cloud.firestore { match /databases/{database}/documents { match /myCollection/{docId} { allow read, write: if request.auth != null; } } } ``` - Attempted to invoke the function manually using Postman, simulating Firestore’s behavior, but it seems like the trigger itself is not firing. I’m using Node.js 14 for the Cloud Functions environment and Firebase SDK version 9.0.0. Is there a specific configuration or limitation I might be overlooking? Any insights on debugging Firestore triggers with Cloud Functions would be greatly appreciated. This is part of a larger CLI tool I'm building. Any help would be greatly appreciated!
