GCP Pub/Sub Messages Not Being Processed by Cloud Run Service Due to 'Invalid Signature' scenarios
I'm learning this framework and Can someone help me understand I'm wondering if anyone has experience with I'm following best practices but Hey everyone, I'm running into an issue that's driving me crazy....... I'm stuck on something that should probably be simple... I'm experiencing an scenario where messages published to Google Cloud Pub/Sub are not being processed by my Cloud Run service. The service logs show an 'Invalid Signature' behavior when it tries to verify the Pub/Sub message signatures. My Cloud Run service is built using Node.js (v14) and is set up to receive messages from a Pub/Sub topic. The subscription is configured to use push delivery, and I'm using the default service account with the 'Pub/Sub Subscriber' role assigned. Here’s the relevant part of my Cloud Run service where I handle the incoming Pub/Sub messages: ```javascript const express = require('express'); const { PubSub } = require('@google-cloud/pubsub'); const app = express(); app.use(express.json()); app.post('/', (req, res) => { const message = req.body.message; // Process the message here console.log(`Received message ID: ${message.messageId}`); res.status(204).send(); }); const PORT = process.env.PORT || 8080; app.listen(PORT, () => { console.log(`Server is running on port ${PORT}`); }); ``` I've verified that the message is being published correctly from another service. However, the Cloud Run service logs show errors like this: ``` behavior: Invalid Signature at PubSub.verifySignature (...) at Object.verifyMessage (...) ``` Additionally, I've double-checked that the Cloud Run service URL is correctly set as the push endpoint in the Pub/Sub subscription settings. I'm not using any custom authentication mechanisms beyond the default service account provided by GCP. Could this scenario be related to the payload format or the way I'm handling the signature verification? Any insights or suggestions for debugging this would be greatly appreciated! Thanks in advance! Thanks in advance! I recently upgraded to Javascript 3.11. Thanks for any help you can provide! I'm developing on Windows 10 with Javascript. Am I missing something obvious? The project is a web app built with Javascript. What would be the recommended way to handle this?
