Uploading Multiple Web Files to Cloud Storage With Python

I am trying to upload multiple web files to a storage bucket using python. I have a service account set up to enable the credentials and so it should be working. However, every time I try to run this code I receive this error:

Forbidden: 403 GET https://storage.googleapis.com/storage/v1/b/voterfile-oh?projection=noAcl: [email protected] does not have storage.buckets.get access to voterfile-oh.

Can I receive help on this issue? I was not able to gather any helpful information from this question nor did the questioner receive an answer that resolved the issue.

def upload_voterfile(bucket_name):
    from google.cloud import storage
    from google.oauth2.service_account import Credentials
    import os
    import json

    credentials_dict = {credentials}
    with open('credentials.json', 'w') as json_file:
        json.dump(credentials_dict, json_file)

    credentials = Credentials.from_service_account_file('credentials.json')

    client = storage.Client(credentials=credentials, project='oh-data-pipeline')
    bucket = client.get_bucket(bucket_name)
