Storage: image upload problem

[melih9779]

When upload file, I get sometimes error

upload:

def upload_to_bucket(blob_name, path_to_file, bucket_name='testBucket'):
    storage_client = storage.Client.from_service_account_json('/home/pi/Desktop/keyfile.json')
    time.sleep(2)
    #print(buckets = list(storage_client.list_buckets())

    bucket = storage_client.get_bucket(bucket_name)
    blob = bucket.blob(blob_name)
    try:
        blob.upload_from_filename(path_to_file)
        blob.make_public()
    except Exception as e:
        return False
    else:
        return True

Error:

The traceback you post is being raised from the cryptography.hazmat package, which has an issue with the same traceback. From the description there, it appears that the service account key in your keyfile.json is corrupt.

Please try generating a new service account key from the Cloud Console.

@melih9779 Have you tried using the sample with a new key?
Is this still an issue?
