Error accessing google cloud storage through python

Question

I need to use python to access files on google cloud storage. I'm using the following code -

from google.cloud import storage
client = storage.Client.from_service_account_json('json/file/path')
bucket = client.get_bucket('demo')

I get the following error -

google.api_core.exceptions.Forbidden: 403 GET https://www.googleapis.com/storage/v1/b/iot-demo?projection=noAcl: [email protected] does not have storage.buckets.get access to demo.

Google Storage JSON API is enabled, I have given the 'storageaccess' account the 'Storage Admin' role. I have also tried giving the 'Project Owner' role.

Is "demo" the real bucket name? If so are you sure you own it? Common names like that are usually owned by someone else from a long time ago. — Mike Schwartz
I just replaced the real bucket name with "demo" for the purpose of asking the question. The bucket I'm using is owned by me, and I have Storage Admin access to it. — Riaz Moradian

I ran into this same issue. My problem was that I created a service account that didn't have sufficient permissions. I deleted the service account and created a new one with the correct permissions. However, I named it the same as the old service account and it seems that GCP was defaulting to the old service account permissions. My solution was to create a new service account with a new name and the right role (Storage Admin) to apply the correct permissions.
