Facing a Google Cloud authentication issue while trying to copy a file to a new cloud storage bucket, resulting in a '401 Anonymous caller does not have storage.objects.create access' error.
Steps to recreate the issue include downloading a cat image using 'wget', followed by attempting to copy the image to a cloud storage bucket using 'gsutil cp' command.
To resolve the issue, users can use 'gcloud auth login' command, follow the prompt to grant permission, receive a key, paste it in Google Cloud Console, and try running the command 'gsutil cp' again.
