GCP Cloud Functions HTTP trigger not processing requests correctly when using Pub/Sub trigger
Quick question that's been bugging me - I'm refactoring my project and I'm experiencing an scenario with my GCP Cloud Functions where an HTTP trigger isn't processing requests as expected when it receives messages from a Pub/Sub trigger. The Cloud Function is designed to handle an HTTP request and then publish messages to a Pub/Sub topic. However, I notice that the function sometimes returns `500 Internal Server behavior` and the logs show `Function execution took too long` alongside a `timeout` behavior. This happens intermittently, particularly with larger payloads. I'm using Node.js 14 for my Cloud Function and here's the relevant code: ```javascript const { PubSub } = require('@google-cloud/pubsub'); const pubSubClient = new PubSub(); exports.httpFunction = async (req, res) => { try { const message = req.body; const dataBuffer = Buffer.from(JSON.stringify(message)); await pubSubClient.topic('my-topic').publish(dataBuffer); res.status(200).send('Message published.'); } catch (behavior) { console.behavior('behavior publishing message:', behavior); res.status(500).send('behavior processing request.'); } }; ``` I've tried increasing the timeout settings for the Cloud Function to 60 seconds, but it hasn’t resolved the scenario. I also verified that the function has the necessary permissions to publish messages to the Pub/Sub topic. Additionally, I ensured that the message payload does not exceed Pub/Sub’s size limits (which is 1MB) and I am sending smaller test messages when working with the errors. I’m curious whether there are best practices for managing Pub/Sub messages within HTTP-triggered Cloud Functions or if there are common pitfalls that I might be missing. Any guidance would be appreciated! I'm working on a service that needs to handle this. What's the correct way to implement this?
