Unity как исправить ошибку десериализации?

using UnityEngine;

    {
        string Filepath = Path.Combine(Application.dataPath + "/Inventory");
        int fileCount = Directory.GetFiles(Filepath).Length;
        path = Path.Combine(Application.dataPath + "/Inventory", "Item0" + ".json");
        string json = File.ReadAllText(path);
        Debug.Log(json);
        Item it = JsonUtility.FromJson<Item>(json);
        list.Add(it);

    }
