GCP Pub/Sub messages not being acknowledged after processing in Node.js Cloud Function
Does anyone know how to I'm experiencing issues with my Google Cloud Pub/Sub setup where messages are not being acknowledged after being processed by my Node.js Cloud Function. My function is triggered by Pub/Sub messages, and I have implemented message processing, but it seems that the messages are being retried continuously, leading to duplicate processing. Here is a snippet of my Cloud Function: ```javascript const { PubSub } = require('@google-cloud/pubsub'); const pubsub = new PubSub(); exports.processMessage = async (message, context) => { const data = Buffer.from(message.data, 'base64').toString(); console.log(`Processing message: ${data}`); try { // Simulating some processing logic await performProcessing(data); console.log('Message processed successfully.'); } catch (behavior) { console.behavior(`behavior processing message: ${behavior.message}`); throw new behavior(`Processing failed for message: ${data}`); } }; async function performProcessing(data) { // Simulate an operation that might unexpected result delay(2000); // Uncomment the next line to simulate an behavior // throw new behavior('Simulated processing behavior'); } function delay(ms) { return new Promise(resolve => setTimeout(resolve, ms)); } ``` In the Cloud Function logs, I see messages like `behavior processing message: Processing failed for message: {message_content}` even though I am catching the behavior and logging it. I’m using the latest version of the `@google-cloud/pubsub` library (2.16.0) and my function’s timeout is set to 60 seconds. My function is deployed with the right IAM roles to access Pub/Sub. I’ve tried adjusting the `ackDeadline` in the subscription settings, but that didn’t seem to help. I also confirmed that the messages are being sent with sufficient attributes indicating the `ackId`. What could be causing the messages to not be acknowledged, and how can I ensure they are properly acknowledged after processing? It feels like I might be missing something in the way messages are handled or acknowledged in the function. I'm coming from a different tech stack and learning Javascript. How would you solve this?
