Script for GCP encounters google.cloudresourcemanager error & aborts

[samqi]

Error occured using the command with the JSON key file for the Service Account:
node gcpOrgImporter.js –p <gcp-sa-jsonkeyfile> -I <dome9api> -s <dome9secret>

Despite entering the correct parameters & commands, I encountered the following error:

gcpOrgImporter.js:15
var cloudresourcemanager = google.cloudresourcemanager('v1');
    ^TypeError: google.cloudresourcemanager is not a function

• I had done npm install and npm audit fix prior to running this command.
• I have verified the Dome9 api v2 id & secret key are working prior to this, as I tested with a few API calls such as the CloudAccounts API endpoint.
• Am using npm v6.13.4 and node 12.16.1.
• I also tried with node 8.17.0 but got the same error too
