Unable to authenticate Google Cloud Storage client in python

I'm trying the following code to access the Google Cloud storage:

client = storage.Client(credentials = GoogleCredentials.from_stream(<path-to-service-account-json>))

Throws this error:

ValueError: This library only supports credentials from google-auth-library-python. See https://google-cloud-python.readthedocs.io/en/latest/google-cloud-auth.html for help on authentication with this library.

I'm able to authenticate discovery.build service using the same credentials(obtained using GoogleCredentials.from_stream()), but for some reason storage.Client fails to use the provided credentials.

Please let me know if I'm missing something.

Got it to work with the following code:

storage_client = storage.Client.from_service_account_json(<path-to-service-account-json>)

Not sure why there are different way to authenticate the discovery API and the storage and other client APIs.
