            Bug ID: 247128
           Summary: Web push notifications sent to web.push.apple.com
                    return 400 BadUrgency
           Product: WebKit
           Version: Safari 16
          Hardware: Unspecified
                OS: macOS 13
            Status: NEW
          Severity: Critical
          Priority: P2
         Component: New Bugs

Safari 16 on MacOS Ventura added support for the Push API.

However the Apple push service has a serious bug that prevents all the push messages from being delivered.

We get this error:

400 Bad Request 
{"reason":"BadUrgency"}

This is clearly a bug in the Apple push service since we use the exact same code (https://github.com/zaru/webpush) to deliver billions of notifications to all the other browsers (Google FCM, Mozilla Autopush, etc.).

The only values that we use for the Urgency header are 'high' or 'normal' and they are both allowed by the standard.

If you need more detailed information we can provide that here or through email (support at pushpad.xyz) if it's more sensitive.

Please investigate this issue or forward this to the right team that manages the Apple push service (web.push.apple.com).
