GCP Pub/Sub subscription not receiving messages after configuration update with Python client
I've been working on this all day and I'm working with an scenario where my Google Cloud Pub/Sub subscription has stopped receiving messages after I updated its configuration... I was using the Python client library version 2.9.0 for this. Initially, everything was working fine, but after adjusting the acknowledgment deadline and adding a filter to process only messages that meet certain attributes, the subscription seems to be dead. I confirmed that the messages are being published successfully, and I can see them in the Pub/Sub metrics, but they are not being delivered to my subscriber. Here’s how I set up the subscription: ```python from google.cloud import pubsub_v1 project_id = 'my-project' topic_id = 'my-topic' subscription_id = 'my-subscription' subscriber = pubsub_v1.SubscriberClient() subscription_path = subscriber.subscription_path(project_id, subscription_id) # Acknowledge deadline of 60 seconds subscriber.update_subscription( subscription=pubsub_v1.types.Subscription( name=subscription_path, ack_deadline_seconds=60, filter='attributes.my_attr = "my_value"" ) ) ``` I also implemented the message processing like this: ```python def callback(message): print(f'Received message: {message.data}') message.ack() streaming_pull_future = subscriber.subscribe(subscription_path, callback=callback) print(f'Listening for messages on {subscription_path}...') ``` Despite this setup, I'm not seeing any logs indicating that the callback function is being triggered at all. I've checked the IAM permissions, and the service account used by the subscriber has the necessary roles. What could be going wrong here? Is there something specific I might be missing with the new filter, or is it possible that the changes in acknowledgment deadline are affecting message delivery? Any insights would be greatly appreciated. This is part of a larger desktop app I'm building. Any feedback is welcome!
