PushManager.subscribe() needs applicatonServerKey option.

Please check the following links: https://tools.ietf.org/html/draft-thomson-webpush-vapid-02#page-6 https://developer.mozilla.org/en-US/docs/Web/API/PushManager/subscribe

I believe option is necessary to send encrypted messages.

The server key is currently used for WebPusher.encode()

The comment says

The server key is an ephemeral ECDH key used only for this transaction

However, I believe this key is not only for this transaction but also for the subscribe method.

to get object data from subscription you can use: JSON.parse(JSON.stringify(subscription))

Sorry, got pulled into a few things. You should be able to call subscription.getKey('auth') from the push subscription object returned by registration.pushManager.subscribe(). If it’s any help, you can look at what I do in the Web Push Data Test Page. I’ll also be honest, I’ve not really checked if I’m being smart about how I do things in pywebpush if you’re not sending data. Mostly because not sending data is a LOT easier. You just do a POST to the endpoint you’ve gotten. No worries about the weird headers, no encryption dance. Heck, you don’t even need to get the various keys from the subscription. All you need to do is pass the VAPID info (if you want, again, not needed) and a TTL (Time To Live for the notification). I’ve got a write up that describes a lot of this (probably in WAY more detail than most folks want) That link drops you off into the “Send A Push Notification With No Data” bit.
