Python Question

Forbidden: 403 User not authorized even though the user is logged in

I am getting 403 error on Mac trying to hit a URL that uses the Python client:

Traceback (most recent call last):

ps = pubsub.Client()
topic = ps.topic(application.config['PUBSUB_TOPIC'])
# topic.project = application.config['PUBSUB_PROJECT']
t_component = Component() = 'topic'
t_component.status = 'UP'
t_component.desc = ('{} exists and is healthy.'
if not topic.exists():
t_component.status = 'DOWN'
t_component.desc = (
'Configured PUBSUB topic ({}) does not exist.'

I created the topic/subscription so I have permissions. My config and gcloud user is correct, I did
gcloud auth ...
and double-checked. I'm the only one getting this error and I did have my personal account used on this laptop to practice the gcloud tutorial. My coworker thought using that other account in the past may cause an issue. I checked my config and the project I'm pointing to, it's the right project. Any help appreciated, thank you


There is a difference between gcloud auth login and gcloud auth application-default login

Re-logging in under gcloud auth application-default login fixed
