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-----

cf-binding-proxy with sveltekit for HMR

I'm using cf-binding-proxy, drizzle ORM, and Sveltekit. I'm using "npx cf-binding-proxy --d1=db" and "npm run dev" at the same time. This is to use HMR of sveltekit. The cf-binding-proxy part continues to rebuild every time the file modifies, making it difficult to access from the npm run dev server. Is there a similar problem or any workaround?
