How to initialize many apps?

[aboutyu]

Hello.

I develop FCM to send 3 apps using this library. but showing follow error messages. How to set this case?

• code const serverKey_10001 = require('../config/pushkey/b.json'); const serverKey_10002 = require('../config/pushkey/a.json'); const fcm_zeroshop = new FCM(serverKey_10001, undefined, 'zeroshop'); const fcm_hidoc = new FCM(serverKey_10002, undefined, 'hidoc');

fcm_zeroshop.send(message, (err, response) => { });

-error message The default Firebase app does not exist. Make sure you call initializeApp() before using any of the Firebase services.

at this time, it's not supported, I recommend you to use the admin.messaging directly as this library is not getting updates anymore
