How to read and reset a pooled token in a pooled token?

SPF

Example token:

public class DrawCardEventToken : PooledProtocolToken
{
    public byte actorID;
    public Card card;
    public override void Read(UdpPacket packet)
    {
        actorID = packet.ReadByte();
        card = packet.ReadToken() as Card; // need help here
    }

    public override void Write(UdpPacket packet)
    {
        packet.WriteByte(actorID);
        packet.WriteToken(card);
    }

    public override void Reset()
    {
        // and here
        throw new System.NotImplementedException();
    }
}

The Card is a pooled token:

public class Card: PooledProtocolToken
{
    public int id;
    public int key;
    public int cost;
    public int attack;
    public int health;
   

    public override void Read(UdpPacket packet)
    {
        id = packet.ReadInt();
        key = packet.ReadInt();
        cost = packet.ReadInt();
        attack = packet.ReadInt();
        health = packet.ReadInt();
    }

    public override void Write(UdpPacket packet)
    {
        packet.WriteInt(id);
        packet.WriteInt(key);
        packet.WriteInt(cost);
        packet.WriteInt(attack);
        packet.WriteInt(health);
    }

    public override void Reset()
    {
        id = default(int);
        key = default(int);
        cost = default(int);
        attack = default(int);
        health = default(int);
    }
   
    static public Card NewCard(int key, int id)
    {
        var card = ProtocolTokenUtils.GetToken<Card>();
        card.key = key;
        card.id = id;
        var settingData = SettingDataMgr.Instance.GetCardSettingData(key);
        card.cost = settingData.cost;
        card.attack = settingData.attack;
        card.health = settingData.health;
        return card;
    }
}

I tried to change the "Card" from "PooledProtocolToken" to "IProtocolToken", but it raised two errors in testing.
Error messages one:

User code threw exception when invoking [DrawCardEvent DrawCardEventToken=]
UnityEngine.Debug:LogError(Object)

Bolt.EventDispatcher:Global_Everyone(Event)
Bolt.EventDispatcher:Dispatch(Event)
Bolt.EventDispatcher:DispatchAllEvents()

Followed by error two:

These two errors appeared after a message that might help:

Hello @SPF ,

Currently, there is no support for using Pooled Tokens inside another Token, so, use the default implementation of the "IProtocolToken" in this case.

You are receiving a "NullReferenceException" on your code, check which reference is missing and see where it should be filled. You need to track it down to where it's missing.
