Facing issue to enable NFC in PkPass

I want to enable NFC in pkpass. I have created a new certificate with NFC check.

I have used below code for pass.json to enable NFC.

pass.nfc = new NFC
{
    message = mbr.MembershipID.ToString(),
    encryptionPublicKey="UU5g65SpyhFa9nJ1nnSiXWU88KZZCb7Ah2iOB/TwuNOMKcMYTY5WdUG7zvK63OEqdaj4P8c7vk7AtBbe+LgnOg==",
    requiresAuthentication = false
};

Now after using this, the pass if not opening. If I use "nfc":[{...}], then it opens the pass, but if I use nfc object as mentioned in the Apple documentation, the pass is not opening.

I am using the below code to generate encryptionPublicKey:

using (ECDiffieHellman ecdh = ECDiffieHellman.Create(ECCurve.NamedCurves.nistP256))
{
    byte[] publicKey = ecdh.ExportSubjectPublicKeyInfo();
    var xCoord = new byte[32];
    var yCoord = new byte[32];
    Array.Copy(publicKey, publicKey.Length - 64, xCoord, 0, 32);
    Array.Copy(publicKey, publicKey.Length - 32, yCoord, 0, 32);
    byte[] rawPublicKey = new byte[64];
    Array.Copy(xCoord, rawPublicKey, 32);
    Array.Copy(yCoord, 0, rawPublicKey, 32, 32);
    string base64PublicKey = Convert.ToBase64String(rawPublicKey);
    Console.WriteLine(base64PublicKey); // Copy this value!
    byte[] decodedKey = Convert.FromBase64String(base64PublicKey);
}

Please guide and let me know where I am going wrong.

I want to enable NFC in my pkpass, I am already using pkpass and its working great, I am using Event Ticket. Now, I want to enable the NFC to my pkpass.
