60706: Invalid Push Token

This error occurs when you register an iOS device for push notifications and the PushToken value is empty or not a valid APNs device token. When you create an apn Binding, use the device token returned by iOS as the Binding Address.

• The app sent an empty PushToken value when it tried to register the device.
• The app converted the APNs device token incorrectly. On iOS 13 and later, parsing [deviceToken description] can produce an invalid token string. Build the token as a hexadecimal string from the raw bytes instead.
• The app tried to create the Binding before iOS finished registering for remote notifications and returned a device token.
• The app's push configuration does not match the app build that generated the token, such as a bundle identifier mismatch.

• Wait until iOS successfully registers for remote notifications, then submit the returned device token when you register the device.
• For apn Bindings, send the APNs device token as the Binding Address. Do not send an empty string, placeholder value, or a token from another push provider.
• Convert the iOS deviceToken from bytes to a hexadecimal string. Do not rely on [deviceToken description] on iOS 13 and later.
• Confirm that your Apple push setup uses an explicit bundle identifier that matches the bundle identifier in Xcode, then register the device again with a fresh token from that app.
