Error: No Firebase App '[DEFAULT]' has been created - call Firebase App.initializeApp()

Question

I have a firebase database linked up to two apps, one being an iOS app and another being a web app coded in node.js which is a basic algorithm that sets data to the database. When ever i am running the algorithm i am confronted with-

Error: No Firebase App '[DEFAULT]' has been created - call Firebase App.initializeApp(). at Error (native) at R (/Users/dd/Desktop/Code/NODE/node_modules/firebase/app-node.js:22:335) at a (/Users/dd/Desktop/Code/NODE/node_modules/firebase/app-node.js:20:68) at Object.c [as database] (/Users/dd/Desktop/Code/NODE/node_modules/firebase/app-node.js:21:447) at Object.

Could someone please help?

Answer 1

You are probably invoking firebase before the app is initialized. All calls to firebase. must come after .initializeApp();

firebase.initializeApp(config);
var db = firebase.firestore();
