Generating push token for device using expo push-notification in bare react native

Question

I am using expo push-notification library to generate device push token and using it to send the notifications to the devices. It is working fine in expo managed workflow but when i am using the function

token = await Notifications.getExpoPushTokenAsync({});

i am getting an error which says :- [Error: Call to function 'ExpoPushTokenManager.getDevicePushTokenAsync' has been rejected. → Caused by: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.notifications. Make sure to call FirebaseApp.initializeApp(Context) first.]

Can anyone please tell how to solve this error? I have tried everything but nothing seems to work.

I have tried to initialize the firebase app using the docs but it did not work as expected and it was giving the same error.

You need to pass the projectId in the object. You can find your projectId in app.json.

docs: https://docs.expo.dev/push-notifications/push-notifications-setup/

  await getExpoPushTokenAsync({
    projectId: "your-project-id"
  })
