MessageError: Error: credential propagation was unsuccessful

Start by reproducing the failure at auth.authenticate_user() and inspect the shown google/colab/auth.py path, especially the call into _message.blocking_request(). Trace read_reply_from_input() in google/colab/_message.py and determine the conditions behind the credential propagation error; done means a verified cause and resolution for this traceback.
