I am a new to Google Cloud Platform. I have setup a Google VM Instance. I am facing an authentication issue on Local Machine while running the command:

Can you please suggest some tips/steps to resolve the same ?

Answer 1

The behavior for application default credentials has changed in gcloud since version 128.

One should use

gcloud auth application-default login

instead.

Note that changing credentials via gcloud auth login or gcloud init or gcloud config set account MY_ACCOUNT will NOT affect application default credentials, they managed separately from gcloud credentials.

Answer 2

Just ran these two commands:

 1. gcloud beta auth application-default login
 2. export GOOGLE_APPLICATION_CREDENTIALS='/<path_to_json>/client_secrets.json'

from local machine and it started working.
