[Question] Does BatchEnforce support a class instance as a value in an IRequestValues object?

What's your scenario? What do you want to achieve?
I have a set of objects, and I want to check if the user has access to these objects based on a given action type. I am using Casbin .NET and the BatchEnforce service, but I always get false. However, when I loop through the set and use Enforce one by one, I get the correct results

Your model:

[request_definition]
r = sub, obj, act

[policy_definition]
p = sub, act, condition, eft

[role_definition]
g = _, _

[policy_effect]
e = some(where (p.eft == allow))

[matchers]
m = g(r.sub, p.sub) && eval(p.condition) &&  (r.act == p.act )

Your policy:

p, 66, Write, r.obj.type == "File" || r.obj.color== "Red", allow
p, 55, Read, r.obj.type == "View", allow

Your request(s):

Here is the object I created that implements IRequestValues :

public class ObjectRequest : IRequestValues
{
    public string Sub{ get; set; }
    public Attributes Obj { get; set; }
    public string Action { get; set; }

    public bool TrySetValue<T>(int index, T value)
    {
        try
        {
            switch (index)
            {
                case 0:
                    Sub= value as string ?? throw new InvalidCastException("Submust be a string");
                    break;
                case 1:
                    Obj=
                        value as Attributes
                        ?? throw new InvalidCastException("Object must be of type Attributes");
                    break;
                case 2:
                    Action = value as string ?? throw new InvalidCastException("Action must be a string");
                    break;
                default:
                    return false;
            }
            return true;
        }
        catch
        {
            return false;
        }
    }

    public string this[int index]
    {
        get
        {
            return index switch
            {
                0 => Sub,
                1 => Obj.ToString(),
                3 => Action,
                _ => throw new IndexOutOfRangeException($"Invalid index: {index}")
            };
        }
    }

    public int Count => 3;
}

And here is the Attributes object definition :

public class Attributes : IRequestValues
{
    public string type{ get; set; }

    public string color{ get; set; }

    public override string ToString()
    {
        return JsonConvert.SerializeObject(this);
    }
}
