JsonException: Max allowed object depth reached while trying to export from type System.Single

So, I was doing some testing with trying to set up nested values in litJSON, and I feel I might have gotten somewhere, but I've run across this error, and have no idea how to solve the issue.

SaveToJSON.cs

 using UnityEngine;
 using System.Collections.Generic;
 using System.IO;
 using System;
 using LitJson;
 
 public class SaveToJSON : MonoBehaviour {
 
     void Update () {
         if (Input.GetKeyDown(KeyCode.O)) {
             PedestalSave();
         } else if (Input.GetKeyDown(KeyCode.P)) {
             PedestalLoad();
         }
     }
 
     void PedestalSave () {
         Pedestal p = new Pedestal();
 
         p.list = new List<IDHolder>();
 
         p.list.Add(new IDHolder() {
             valueName = "id",
             valueInt = 0,
         });
 
         p.list.Add(new IDHolder() {
             valueName = "aggression",
             valueBool = false
         });
 
         string json_p = JsonMapper.ToJson(p);
 
         Debug.Log(json_p);
 
         File.WriteAllText(Application.dataPath + "/Saves/test.json", json_p);
     }
 
     void PedestalLoad () {
         string jsonString = File.ReadAllText(Application.dataPath + "/Saves/test.json");
         JsonData jsonData = JsonMapper.ToObject(jsonString);
 
         Debug.Log(jsonData["list"][0]["power"]);
     }
 }
 
 public struct Pedestal {
     public List<IDHolder> list { get; set; }
 }
 
 [Serializable]
 public struct IDHolder {
     public string valueName { get; set; }
     public string valueString { get; set; }
     public int valueInt { get; set; }
     public float valueFloat { get; set; }
     public bool valueBool { get; set; }
 }

Any ideas on how to fix this, or if I'm just a noob, and I'm completely missing something so obvious?
