GCP Pub/Sub messages not being delivered to Cloud Functions with 'Message ID not found' scenarios
I'm building a feature where I'm stuck on something that should probably be simple... I'm working with an scenario where messages published to a Google Cloud Pub/Sub topic are not being delivered to my Cloud Function. Instead, I'm seeing the behavior 'Message ID not found' in the logs. I have a Cloud Function that is triggered by a Pub/Sub topic, and although I can see messages being published successfully in the Pub/Sub dashboard, they do not seem to invoke the function as expected. My Cloud Function is defined as follows: ```javascript const { PubSub } = require('@google-cloud/pubsub'); exports.processMessage = (message, context) => { const data = Buffer.from(message.data, 'base64').toString(); console.log(`Received message: ${data}`); }; ``` I've checked the IAM permissions, and the Cloud Function service account has the necessary Pub/Sub Subscriber role on the topic. I also verified that the Cloud Function is deployed with the correct topic name and that the function is enabled. The function is set to use the default maximum timeout of 60 seconds, which I thought should be sufficient for processing. I also tried redeploying the function and confirmed that there are no unhandled exceptions or errors in the function code itself. However, the scenario continues. I would appreciate any insights into what might be going wrong or if there are any specific configurations I might be overlooking that could cause this delivery failure. I'm working on a service that needs to handle this. What's the best practice here? The project is a application built with Javascript.
