Firebase Admin Auth Token Revoked

Question

I am attempting to implement a node.js server to listen to changes in my firebase database. This is my code to initialize the server:

var admin = require('firebase-admin');
var serviceAccount = require('./SERVICE-ACCOUNT.json');

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: "https://APP-NAME.firebaseio.com"
});

var db = admin.database();
admin.database.enableLogging(true);
var convRef = db.ref('conversations');
convRef.once('value', function(snapshot) {
  console.log("VALUE: " + snapshot.val());
}, function(error) {
  console.log("ERROR: " + error.code);
});

With debugging enabled, I receive the errors:

p:0: Auth token refreshed

Answer 1

I realized I created my service account in the wrong place. Since I wasn't the owner of the project, it wasn't valid. I got the owner of the project to create a service account for me and everything works now.
