Chrome notification with rails - 400 UnauthorizedRegistration

Question

I`m using Rails and https://github.com/zaru/webpush gem and have configured things according to this guide https://rossta.net/blog/web-push-notifications-from-rails.html

I manage to register ServiceWorker and get subscription. I save it like this in controller

endpoint = params[:subscription][:endpoint]
p256dh = params[:subscription][:keys][:p256dh]
auth = params[:subscription][:keys][:auth]

current_user.gcm_endpoint = endpoint
current_user.gcm_p256dh = p256dh
current_user.gcm_auth = auth

Later I send the message like this:

message = {
    title: "Title",
    body: "This is a test notification",
    icon: "images/my-128.png"
}

Webpush.payload_send(
    endpoint: current_user.gcm_endpoint,
    message: JSON.generate(message),
    p256dh: current_user.gcm_p256dh,
    auth: current_user.gcm_auth,
    ttl: 600,
    api_key: "<MY API KEY>"
)

I have configured and activated account on Google Console. I have turned on GCM API and added a correct key. But no matter what I do, I receive this 400 error code. And I have no stats in Google console - as if no calls are made to my API call.

The problem was in the key itself. Need to generate it using a separate Firebase control panel. Here With that key my code works well.
