Google Cloud Platform Pub/Sub Cloud Functions JavaScript

I've looked through the documentation and I'm still confused about I'm working on a personal project and I'm experiencing an scenario with my Google Cloud Function that is triggered by a Pub/Sub subscription... Despite having the correct configurations, my function is not receiving messages as expected. I've created a Pub/Sub topic and a subscription, and I can see the messages being published to the topic. However, the Cloud Function logs show multiple entries of 'Message Not Acknowledged' and the messages remain unacknowledged. Here's a snippet of my Cloud Function code using Node.js: ```javascript const { PubSub } = require('@google-cloud/pubsub'); exports.myFunction = async (message, context) => { const data = Buffer.from(message.data, 'base64').toString(); console.log(`Received message: ${data}`); // Simulating processing time await new Promise(resolve => setTimeout(resolve, 5000)); // 5 seconds delay }; ``` I verified that the function is deployed successfully, and the triggers are set up correctly in the GCP console. My subscription is configured with 'Pull' and uses the default acknowledgment deadline of 10 seconds. The question seems to be occurring because my function takes longer than the acknowledgment deadline to process the messages. I tried increasing the acknowledgment deadline to 60 seconds in the subscription settings, but I still see the same behavior. I also checked the IAM permissions, and the service account for the Cloud Function has the `pubsub.subscriber` role assigned. I’m not sure if I’m missing something in my configuration or if there’s a better way to handle longer processing times. Any advice or best practices would be greatly appreciated! I'm using Javascript 3.9 in this project. Any ideas what could be causing this?
