Could not load the default credentials? (Node.js Google Compute Engine tutorial)

Question

SITUATION:

I follow this tutorial: https://cloud.google.com/nodejs/tutorials/bookshelf-on-compute-engine

Everything works fine until I do

For all people using firebase, what it worked for me was passing the credentials to the KeyManagementServiceClient constructor

const serviceAccount = require('../keys/file.json'); //<- your firebase credentials
const client = new KeyManagementServiceClient({
      credentials: serviceAccount,
    });
