Serializing a dictionary to json using LitJson.

In my game players can customize their characters by changing the characters color and accessory. So I am trying to save this customization data as a Json to a text file. Here is my code: using UnityEngine; using System.Collections.Generic; using System.IO; using System; using LitJson;

 public class SnakeCustomizationStorage : IFileStorage{
 
     private static string CUSTOMIZATION_FILENAME = "/snakeCustomization.dat";
     private static string FILEPATH = Application.persistentDataPath + CUSTOMIZATION_FILENAME;
     private static SnakeCustomizationStorage m_instance;
     private static Dictionary<string, CustomizationData> m_customData = new Dictionary<string, CustomizationData>();
     private static JsonData m_jsonData = new JsonData();
 
     public static SnakeCustomizationStorage Instance {
         get {
             if(m_instance == null) {
                 m_instance = new SnakeCustomizationStorage();
                 Environment.SetEnvironmentVariable("MONO_REFLECTION_SERIALIZER", "yes");
             }
             return m_instance;
         }
     }
 
     #region IFileStorage implementation
     public void load()
     {
         if(File.Exists(FILEPATH)) {
             string fileText = File.ReadAllText(FILEPATH);
             m_customData = JsonMapper.ToObject<Dictionary<string, CustomizationData>>(fileText);
         } else {
             List<SnakeMysteryReward> unlockedSnakes = RewardManager.Instance.getGrantedSnakeRewards();
             for(int i = 0; i < unlockedSnakes.Count; i++) {
                 string name = unlockedSnakes[i].productName;
                 CustomizationData data = new CustomizationData(GreedyConstants.DEFAULT_SNAKE_GREEN, "");
                 m_customData.Add(name, data);
             }
             save();
         }
     }
 
     public void save()
     {
         JsonData json = JsonMapper.ToJson(m_customData);
         File.WriteAllText(FILEPATH, json.ToString());
     }
 
     public string getFilePath()
     {
         return FILEPATH;
     }
     #endregion
 }
 
 
 [System.Serializable]
 class CustomizationData {
     public float [] color;
     public string accessory;
 
     public CustomizationData(Color snakeColor, string accessoryName) {
         color = new float[] {
                                 snakeColor.r,
                                 snakeColor.g,
                                 snakeColor.b,
                                 snakeColor.a
                             };
         accessory = accessoryName;
     }
 }

No matter what I try, I am not able to figure out how to get the dictionary serialized into the Json string. The code to convert it does not seem to work. What am I doing wrong? The format of Json I am looking to generate is: { "Name1" : {"accessory":"hat1", "color":[108, 0, 234, 1]}, "Name2" : {"accessory":"hat2", "color":[108, 0, 234, 1]} }

Basically key value pairs of the character name and the customization data. Any help is appreciated thanks.
