push event not triggered in service worker - push-notification

Question

Following this tutorial until "Handle push event" section to setup a desktop notification system in my application, I face a problem:
When I click "push" to push a notification artificially with Chrome, no notification appear. No message in the console.
I allowed the notification from the website and the service-worker is well installed in my browser.
My service worker looks like this:
self.addEventListener('push', function (event) {
console.log('[Service Worker] Push Received.')
console.log(`[Service Worker] Push had this data: "${event.data.text()}"`)
const title = 'My App Name'
const options = {
body: event.data.text(),
icon: 'pwa/icon.png',
badge: 'pwa/badge.png'
}
const notificationPromise = self.registration.showNotification(title, options)
event.waitUntil(notificationPromise)
})
and my service worker registration (using register-service-worker npm package) looks like this:
import { register } from 'register-service-worker'
const applicationServerPublicKey = 'BI5qCj0NdNvjDcBYTIXiNccdcP74Egtb3WxuaXrHIVCLdM-MwqPkLplHozlMsM3ioINQ6S_HAexCM0UqKMvaYmg'
function urlB64ToUint8Array (base64String) {
const padding = '='.repeat((4 - base64String.length % 4) % 4)
const base64 = (base64String + padding)
.replace(/\-/g, '+')
.replace(/_/g, '/')
const rawData = window.atob(base64)
const outputArray = new Uint8Array(rawData.length)
for (let i = 0; i < rawData.length; ++i) {
outputArray[i] = rawData.charCodeAt(i)
}
return outputArray
}
async function manageNotificationSubscription (registration) {
const subscription = await registration.pushManager.getSubscription()
let isSubscribed: boolean = !(subscription === null)
if (isSubscribed) {
console.log('User IS subscribed.')
} else {
console.log('User is NOT subscribed.')
const applicationServerKey = urlB64ToUint8Array(applicationServerPublicKey)
try {
await registration.pushManager.subscribe({
userVisibleOnly: true,
applicationServerKey: applicationServerKey
})
console.log('User just subscribed.')
} catch (e) {
console.error('Failed to subscribe the user: ', e)
}
}
}
if (process.env.NODE_ENV === 'production') {
register(`${process.env.BASE_URL}service-worker.js`, {
ready () {
console.log(
'App is being served from cache by a service worker.'
)
},
async registered (registration) {
console.log('Service worker has been registered.')
await manageNotificationSubscription(registration)
},
cached () {
console.log('Content has been cached for offline use.')
},
updated () {
console.log('New content is available; please refresh.')
},
offline () {
console.log('No internet connection found. App is running in offline mode.')
},
error (error) {
console.error('Error during service worker registration:', error)
}
})
}
It looks like the push event in the service-worker is not even triggered...
Did I do something wrong?
