[marketplace-integrated-saas]: create_subscription from https://developers.google.com/gcp-marketplace-saas#3 is out of date

[xavier-rbz]

Preliminary steps: I created a fresh python venv, then installed prerequisites using pip install --upgrade google-api-python-client google-cloud google-cloud-pubsub.

In https://developers.google.com/gcp-marketplace-saas#3, the provided create_subscription.py doesn't work out of the box:

1. it uses a programming API that seemingly doesn't exist anymore

   Traceback (most recent call last):
   File "create_subscription.py", line 61, in <module>
   main(sys.argv)
   File "create_subscription.py", line 38, in main
   topic_path = subscriber.topic_path(TOPIC_PROJECT,

2. subscriber.create_subscription now requires the name and topic arguments to be passed as keywords: its signature is create_subscription(request: google.cloud.pubsub_v1.types.Subscription = None, *, name: str = None, topic: str = None, push_config: google.cloud.pubsub_v1.types.PushConfig = None, ack_deadline_seconds: int = None, retry: google.api_core.retry.Retry = <object object>, timeout: float = None, metadata: Sequence[Tuple[str, str]] = ()) according to https://googleapis.dev/python/pubsub/latest/subscriber/api/client.html#google.cloud.pubsub_v1.subscriber.client.Client.create_subscription

Cheers

May I know the python version you are using?

[xavier-rbz]

I'm using Python 3.8.6 on Linux

I was able to create a subscription by running python create_subscription.py. Though my python is 2.7.16. It seems the api is still working.

xavier, have you done the following steps as described in https://developers.google.com/gcp-marketplace-saas#1?

• create service account and grant it pub/sub editor;
• download a JSON key for the service account;
• set environment variables: GOOGLE_CLOUD_PROJECT and GOOGLE_APPLICATION_CREDENTIALS.

If you have, I am going to test it in a fresh python3 env.

I am going to close this issue since no response for 18 days. Please feel free to reopen it if you still face the same problem.

Pinning google-cloud-pubsub to 1.4.0 on Python 3.8 got me around the issue to run the one-off script.

Thank you flebel for sharing this.
