JsonReaderException when parsing List<Class> in Nancy

Question

I am building a P2P Network with nancy. So far everything has gone fine. Now i am building my fingertables and want to parse them on using to other clients. But I get the following error:

Newtonsoft.Json.JsonReaderException: Unexpected character encountered while parsing value

My Request:

using (HttpClient client = new HttpClient())
{
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    HttpResponseMessage response = await client.GetAsync($"http://localhost:{port}/Successor/{id}");
    var chord = await response.Content.ReadAsAsync<ChordNode>();
    return chord;
}

which just returns:

Get["Successor/{id}", true] = async (x, ct) =>
{
    return _chordNode;
};

My class ChordNode worked fine until i added FingerTable list. It looks like the following:

public class ChordNode
{

    public NodeInfo Info { get; set; }

    public NodeInfo Successor { get; set; }
    public NodeInfo Predecessor { get; set; }
    public List<ChordNode> FingerTable { get; set; }

    ..... and other stuff thats not important.

If i make FingerTable private, it works again, but then i don't get my FingerTable returned to the other clients.

Still pretty new to asking questions on StackOverflow. So any feedback would be nice :)

Answer 1

I found a solution. After i removed all my ASYNC i got a better message telling me i used this part wrong.

Get["Successor/{id}", true] = async (x, ct) =>

i used my parameter x.id as a int in a method call and it gave me no feedback whatsoever. So after parsing this to a int it solved everything thing.

Thanks for all the nice feedback.
