KeyNotFoundException: The given key was not present in the dictionary.
Im a new unity user and i was trying to make a simple inventory system with a tutorial. I have seen other questions about this and fixes, and it is all about a mistake or a missing coma, but i have scanned my JSON a few times and i cant find it.
[
{
"id": 0,
"title": "Pistol",
"weight": 1,
"damage": 25
}
{
"id": 1,
"title": "Magnum",
"weight": 2,
"damage": 32
}
{
"id": 2,
"title": "SniperRifle",
"weight": 4,
"damage": 195
}
{
"id": 3,
"title": "AK",
"weight": 3,
"damage": 38
}

}

}

Here is the error:
KeyNotFoundException: The given key was not present in the dictionary.

Here is my c# item database script.
using UnityEngine;
using System.Collections;
using LitJson;
using System.Collections.Generic;
using System.IO;
public class itemDatabase : MonoBehaviour {
private List<Item> database = new List<Item> ();
private JsonData itemData;
void Start()
{
itemData = JsonMapper.ToObject (File.ReadAllText(Application.dataPath + "/StreamingAssets/Items.json"));
ConstructItemDatabase ();
Debug.Log (database[1].Title);
}
void ConstructItemDatabase()
{
for (int i = 0; i < itemData.Count; i++)
{
database.Add(new Item((int)itemData[i]["id"], itemData[i]["title"].ToString(), (int)itemData[i]["damage"], (int)itemData[i]["weight"]));
}
}
}
public class Item
{
public int ID { get; set; }
public string Title { get; set; }
public int Damage { get; set; }
public int Weight { get; set; }
public Item(int id, string title, int damage, int weight)
{
this.ID = id;
this.Title = title;
this.Damage = damage;
this.Weight = weight;
}
}
All help will be appreciated.

I believe what the answer is pointing out is that you're missing a few commas.
