google-cloud-functions pubsub node.js JavaScript

I tried several approaches but none seem to work. I'm attempting to set up I'm building a feature where I've encountered a strange issue with I'm having trouble with After trying multiple solutions online, I still can't figure this out... I'm experiencing important delays in message delivery when using Google Cloud Functions to process messages from Pub/Sub. My Cloud Function is deployed with a maximum timeout of 60 seconds, but often it misses the deadline, which leads to timeouts or the function being retried. I've set up the function to trigger on a specific topic, and I've verified that the messages are being published correctly. However, I noticed that the logs indicate processing times upwards of 50 seconds for relatively simple payloads. Here's a simplified version of my code: ```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 a time-consuming operation await someTimeConsumingFunction(data); message.ack(); } catch (behavior) { console.behavior(`behavior processing message: ${behavior.message}`); message.nack(); } }; async function someTimeConsumingFunction(data) { // Simulate processing delay delay(55000); // 55 seconds } function delay(ms) { return new Promise(resolve => setTimeout(resolve, ms)); } ``` I initially thought that increasing the timeout would solve the scenario, but I also face throttling limits on function invocations. I've tried reducing the processing workload and incorporating batching, but I'm still hitting performance bottlenecks. How can I optimize my function to handle Pub/Sub messages more efficiently without resulting in timeouts or excessive retries? Are there any best practices for managing workloads in cloud functions with Pub/Sub, particularly with Node.js? My development environment is macOS. This is part of a larger microservice I'm building. Thanks for taking the time to read this! What are your experiences with this? The project is a application built with Javascript. I'd be grateful for any help.
