C# NewtonSoft DeserializeObject error

问题

The strange thing is that it works fine on my local deploy (Win 10 IIS) but when I deploy it to our UAT server, it goes nuts.

I'm trying to deserialize the following json string:

{
  "header": {
    "application-code": "ZZZ"
  },
  "piece": [
    "0000001"
  ]
}

The classes that represent this are defined:

public class RequestPiece
{
    [JsonProperty(PropertyName = "header")]
    public RequestHeaderPiece requestheader { get; set; }
}

public class ResponseHeaderPiece
{
    [JsonProperty(PropertyName = "application-code")]
    public string application_code { get; set; }
}

public class ResponsePiece
{
    [JsonProperty(PropertyName = "header")]
    public ResponseHeaderPiece responseheader { get; set; }
    [JsonProperty(PropertyName = "piece")]
    public List<string> piece { get; set; }
}

Now, when I run this code:

        public List<string> getP(string pieces)
    {
        try{
            restAPI.Url = config.PieceServiceUrl + "/" + pieces;
            restAPI.Method = "GET";
            restAPI.ClientId = config.ClientId;
            restAPI.Secret = config.SecretKey;
            string returnString = restAPI.callJsonService();
            log.Info(System.Reflection.MethodInfo.GetCurrentMethod() + "::JSON response  => " + returnString);
            ResponsePiece rp = JsonConvert.DeserializeObject<ResponsePiece>(returnString);
            log.Info(System.Reflection.MethodInfo.GetCurrentMethod() + "::JSON response " + rp.piece);
            return rp.piece;
        }
        catch (Exception ex)
        {
            log.Error(System.Reflection.MethodInfo.GetCurrentMethod() + "::failed::" + ex.Message.ToString() + " => " + ex.StackTrace.ToString());
            return null;
        }
    }

JsonConvert.DeserializeObject is returning the following error:

Again, I run the same publish on my local IIS without a problem, so I'm completely stuck.
