Cannot get public keys for jwks verification

I am using the public url https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/jwsPublicKeys to get the jwks keys to verify the signed payload for store kit payments. I am checking Apple server notifications.

const APPLE_JWKS_URL = "https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/jwsPublicKeys"

// Apple JWK set (cached by jose)
const appleJWKS = createRemoteJWKSet(new URL(APPLE_JWKS_URL));
const jwks = await appleJWKS();
logger.debug("Apple JWKS Keys: %O", jwks); // Log the keys
if (!signedPayload) {
  // return res.status(400).json({ error: "Missing signedPayload" });
}

// Step 1: Verify JWS (signature + payload) using Apple's JWKS
const { payload, protectedHeader } = await jwtVerify(
  signedPayload,
  appleJWKS,
  {
    algorithms: ["ES256"], // Apple uses ES256 for signing
  }
);
