Problem on Streaming the data to google cloud datastore

I am following the tutorial in this Particle doc.
https://docs.particle.io/tutorials/integrations/google-cloud-platform/#storing-data-in-a-datastore-database
However, when I follow to the last step on running the script npm install and node tutorial.js


The terminal only Show Authenticating with Google Cloud… and Authentication successful.
The terminal stops at here without any feedback.
Have any deal with this in past?
Thank you.
