FCM Web send message succeeds but nothing appears in Browser

I am sending following Notification
Authorization:key=A.....
Content-Type:application/json
{
"to" : "cBx_ErhkhNw:APA91bEzwHvZ2daEK15Y3A0VAprxPV-4GGq10FjlrFnHzCs8xSJXz2lATjh9AoLRQvnSseT6r4ggApC6TbtD9M_sI_BDDmycZ1TEVn0HaF5pAABeSbHqcOK-kmkPqOve1VThUaUIXQy4",
"notification": {
"title": "Test Nachricht",
"body": "This is a message from FCM to web"
},
"priority": "high",
"webpush": {
"fcm_options": {
"link": "https://dummypage.com"
}
}
}
And have following code:
app.js
// Initialize Firebase
var config = {
apiKey: "<KEY>",
authDomain: "<AUTH_DOMAIN>",
databaseURL: "<DB_URL>",
projectId: "atlas-test-35d33",
storageBucket: "<STORAGE_BUCKET>",
messagingSenderId: "817272374311"
};
firebase.initializeApp(config);
const messaging = firebase.messaging();
messaging.usePublicVapidKey("<PUBLIC_KEY>");
messaging.requestPermission()
.then(function() {
console.log("Permission granted");
return messaging.getToken()
})
.then(function(token) {
console.log(token)
})
.catch(function(err) {
console.log(err)
})
console.log("listenting")
messaging.onMessage(function(payload) {
console.log('Message received. ', payload);
// ...
});
firebase-messaging-sw.js
// Give the service worker access to Firebase Messaging.
// Note that you can only use Firebase Messaging here, other Firebase libraries
// are not available in the service worker.
importScripts('https://www.gstatic.com/firebasejs/5.9.0/firebase-app.js');
importScripts('https://www.gstatic.com/firebasejs/5.9.0/firebase-messaging.js');
var config = {
apiKey: "<KEY>",
authDomain: "<AUTH_DOMAIN>",
databaseURL: "https://atlas-test-35d33.firebaseio.com",
projectId: "atlas-test-35d33",
storageBucket: "<STORAGE_BUCKET>",
messagingSenderId: "817272374311"
};
firebase.initializeApp(config);
// Retrieve an instance of Firebase Messaging so that it can handle background
// messages.
const messaging = firebase.messaging();
When I try to send a Notification to the fcm Server I get following response:
{
"multicast_id": 5394725759940263108,
"success": 1,
"failure": 0,
"canonical_ids": 0,
"results": [
{
"message_id": "0:1552646324437940%e609af1cf9fd7ecd"
}
]
}
Which seems, like everything is fine for me. But I dont receive anything in my Web application. I just hardcoded the "to" token for testing purposes but I dont think thats the Problem.
Do you have any clue whats the problem, or is there any debug possibility.
Thanks!

Write to Firebase Storage with JavaScript gives "Cross-Origin Request Blocked"

I have made a web app which includes a form with two fields and what I want to happen is when I click the button, my data should be written to Firebase. So I made an onclick function which writes to Firebase, the function is called but it doesn't write to Firebase. I get this error message:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at
https://firebasestorage.googleapis.com/v0/b/storymap-da000.appspot.com/o?name=11-2-2018-0-6-27.
(Reason: CORS request did not succeed).[Learn More]
My vanilla JavaScript code:
var config = {
apiKey: "XXX",
authDomain: "XXX",
databaseURL: "XXX",
projectId: "XXX",
storageBucket: "XXX",
messagingSenderId: "XXX"
};
firebase.initializeApp(config);
window.addEventListener('load', function() {
const fileButton = document.getElementById("fileButton");
const up = document.getElementById("up")
});
fileButton.addEventListener('change', function(e){
var file = e.target.files[0];
var storageRef = firebase.storage().ref(image_name);
storageRef.put(file)
});
up.onclick=function(){
var lat = new URL(location.href).searchParams.get("lat")
var lng = new URL(location.href).searchParams.get("lng")
var title = document.getElementById("title").value
var story = document.getElementById("story").value
var database = firebase.firestore()
database.collection("Stories").add({
title:title,
story:story,
lat: lat,
lng:lng,
url:image_name});}
Any ideas?

i think you need to register your domain in your firebase app

Firebase error on web token notification

I am trying to send the notification to the specific user using firebase. Going on with tutorials, I could not solve this in the beginning phase.
Here is my js:
var config = {
apiKey: "",
authDomain: "",
databaseURL: "",
projectId: "",
storageBucket: "",
messagingSenderId: ""
};
firebase.initializeApp(config);
const messaging = firebase.messaging();
messaging.usePublicVapidKey("");
messaging.requestPermission().then(function() {
console.log('Notification permission granted.');
return messaging.getToken();
}).then(function(token){
console.log(token);
})
function getRegToken(){
messaging.getToken().then(function(currentToken) {
if (currentToken) {
// sendTokenToServer(currentToken);
console.log(currentToken);
} else {
// Show permission request.
console.log('No Instance ID token available. Request permission to generate one.');
setTokenSentToServer(false);
}
}).catch(function(err) {
console.log('An error occurred while retrieving token. ', err);
showToken('Error retrieving Instance ID token. ', err);
setTokenSentToServer(false);
});
}
I have inserted correct parameters inside the config and public key

create users on firebase using its authenticate methods

i tried sending the credentials and this error appears.
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://www.googleapis.com/identitytoolkit/v3/relyingparty/signupNewUser?key=*******. (Reason: CORS request did not succeed).
(function () {
var config = {
apiKey: "*******",
authDomain: "*******",
databaseURL: "*******",
projectId: "*******",
storageBucket: "*******",
messagingSenderId: "*******"
};
firebase.initializeApp(config);
const email = document.getElementById('email');
const password = document.getElementById('password');
const btnSignUp = document.getElementById('btnSignUp');
btnSignUp.addEventListener('click', e => {
const mail = email.value;
const pass = password.value;
firebase.auth().createUserWithEmailAndPassword(mail, pass).catch(function(error) {
var errorCode = error.code;
var errorMessage = error.message;
if (errorCode == 'auth/weak-password') {
alert('The password is too weak.');
} else {
alert(errorMessage);
}
console.log(error);
});
});
}());
How do I solve the CORS request blocked?

Your firebase imports are wrong, use this:
<!-- Firebase App is always required and must be first -->
<script src="https://www.gstatic.com/firebasejs/5.1.0/firebase-app.js"></script>
<!-- Add additional services that you want to use -->
<script src="https://www.gstatic.com/firebasejs/5.1.0/firebase-auth.js"></script>

FCM Cannot receive messages on WebApp

Well, simply put, I cannot receive messages via my WebApp using JS. I am receiving tokens and I am able to send messages via Firebase console to the WebApp's token, but I am not getting any receiving.
Here is my JS Code:
var config = {
apiKey: "AIzaSyBLCsBQVXLsDjPhjdkvJVMGyDUcfWrFtQU",
authDomain: "php-test-project-78c66.firebaseapp.com",
databaseURL: "https://php-test-project-78c66.firebaseio.com",
projectId: "php-test-project-78c66",
storageBucket: "php-test-project-78c66.appspot.com",
messagingSenderId: "856365479454"
};
firebase.initializeApp(config);
$(document).ready(function(){
const messaging = firebase.messaging();
messaging.requestPermission().then(function() {
console.log("Permitted");
return messaging.getToken();
}).then(function(token) {
console.log(token);
}).catch(function(error) {
console.log("Not Permitted");
});
messaging.onMessage(function(payload) {
console.log("TEST");
console.log("Message received. ", payload);
});
});
Upon sending message via Firebase Console, I do not receive anything. I send by using TokenID.
PS: The keys are of a Dev Testing App, hence I kept it in. If admins consider this a problem then you may remove it.
