google-cloud-pubsub cloud-functions node.js JavaScript

I'm trying to implement I'm working on a project and hit a roadblock. I'm experiencing a frustrating scenario with GCP Pub/Sub in my Node.js Cloud Function. The function processes messages correctly, but I'm seeing a important delay in acknowledging messages, which leads to re-delivery. My configuration is set up as follows: ```javascript const { PubSub } = require('@google-cloud/pubsub'); const pubsub = new PubSub(); exports.processMessage = (message, context) => { const msgData = Buffer.from(message.data, 'base64').toString(); console.log('Processing message:', msgData); // Simulating a lengthy process setTimeout(() => { // Acknowledge the message message.ack(); }, 10000); // Acknowledging after 10 seconds }; ``` The question is that the function is timing out after 60 seconds, even though the message is processed correctly, leading to the same message being pushed again. I've ensured that the Pub/Sub subscription is set to `ackDeadlineSeconds` of 30 seconds, but it seems like my message acknowledgement is occurring too late. I've tried increasing the `ackDeadlineSeconds` to 90 seconds, but I'm still running into re-delivery issues. I also attempted to restructure the acknowledgment logic, but the function still doesn't acknowledge the message before the timeout. I'm using Node.js version 14 and the latest @google-cloud/pubsub library version 2.22.0. What can I do to handle the message processing without running into this re-delivery scenario? Is there any best practice for managing long-running tasks with Pub/Sub in Cloud Functions? Any help would be greatly appreciated! For context: I'm using Javascript on Ubuntu. For context: I'm using Javascript on Windows 11. Any pointers in the right direction?
