FCM error

[mojjjtaba]

I want to use FCM but I'm getting this error:

C5Z_9JJW.js:359 Uncaught (in promise) FirebaseError: Messaging: A problem occurred while subscribing the user to FCM: Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project. (messaging/token-subscribe-failed).

getToken is not running at all.

here is the code:

const firebaseApp = useFirebaseApp()
console.log("firebaseApp", firebaseApp)
const messaging = getMessaging(firebaseApp)

const token = ref('')


Notification.requestPermission().then((permission) => {
// alert(permission)

if (permission === 'granted') {
	new Notification("Hello", {
		icon: "https://logos-world.net/wp-content/uploads/2020/04/Huawei-Logo.png",
		body: 'This is body'
	})
}
})

getToken(messaging, {
vapidKey: "BAD_..."
}).then((currentToken) => {
console.log("currentToken", currentToken)
token.value = currentToken
})
