Hi @SaschaHeyer,

Would you mind doing a pip freeze and providing the exact stack trace?

The most likely cause is an old version of google-auth. See #933

@SaschaHeyer This is because you have an old google-auth installed, please update the google-auth library to the latest version (1.16.1). Please reopen the issue if it doesn't work. Thanks.
