Help Needed: APNS Push Notification ES256 JWT Error

Hello, I'm trying to implement Apple Push Notification Service (APNS) in my app and encountering a JWT authentication error. I need some assistance. Problem Description When trying to send push notifications, I get the following error:

{
  "jse_shortmsg": "Failed to generate token",
  "jse_cause": {},
  "jse_info": {},
  "message": "Failed to generate token: secretOrPrivateKey must be an asymmetric key when using ES256"
}

{
  "jse_shortmsg": "Failed to generate token",
  "jse_cause": {},
  "jse_info": {},
  "message": "Failed to generate token: secretOrPrivateKey must be an asymmetric key when using ES256"
}

What I've Tried I've generated certificates and keys from my Apple Developer account and downloaded the p8 file. I'm trying to authenticate to APNS using this key. Looking at the error message secretOrPrivateKey must be an asymmetric key when using ES256, it seems that when generating the JWT token using the ES256 algorithm, the provided key is either not in the correct asymmetric key format or is not being loaded properly. this is p8 file content < Private Key input value -----BEGIN PRIVATE KEY----- (codes) -----END PRIVATE KEY-----

Thanks Pawan, I'll be waiting for the update! novu is a really cool service. I want to use novu pro, but I have difficulty setting up my service because of an APNS error. Is there any update I can refer to?
