GCP Pub/Sub Messages Not Retained After Subscription Acknowledgment in Node.js
After trying multiple solutions online, I still can't figure this out... I'm experiencing an scenario with GCP Pub/Sub where messages are not being retained after my subscription acknowledges them. I'm using the `@google-cloud/pubsub` library version `2.16.0` in my Node.js application. The messages are published successfully, and my subscription's acknowledgment deadline is set to `10 seconds`, but once acknowledged, the messages disappear, and I'm unable to retrieve them again, even though the Pub/Sub settings indicate that they should be retained for a week. Here's a snippet of my subscriber code: ```javascript const { PubSub } = require('@google-cloud/pubsub'); const pubsub = new PubSub(); const subscriptionName = 'my-subscription'; const subscription = pubsub.subscription(subscriptionName); const messageHandler = message => { console.log(`Received message: ${message.id}`); // Process the message message.ack(); // Acknowledge the message }; subscription.on('message', messageHandler); ``` I've tried checking the settings in the Google Cloud Console for my subscription and the retention policy, and everything looks fine. I also verified that I'm not inadvertently deleting messages elsewhere in my code. Are there any specific configurations or best practices I might be missing that could cause this behavior? Additionally, when I check the monitoring metrics for the subscription, I see that messages are being published and acknowledged, but the `acknowledgedMessageCount` is increasing without any errors reported. Any insights would be greatly appreciated! This is for a service running on Windows 10. Thanks for taking the time to read this!
