Error Index was out of range

So, I'm trying to create an item in a case that gives RP from the ServerRewards plugin. I must not be doing something right. here are my item objects within the Items key.

{
          "Display Name (for display in the interface)": "RP x100,000",
          "ID": 0,
          "Chance": 0.1,
          "Item type": "Command",
          "Image (if empty - the icon is taken by shortname) ": "https://i.imgur.com/nJqsuZT.png",
          "Display name (for the item) (if empty - standard)": "RP x100,000",
          "Shortname": "",
          "Skin": 0,
          "Amount (for item)": 1,
          "Command": "sr add {userid} 100000",
          "Plugin": {
            "Hook to call": "AddPoints",
            "Plugin name": "ServerRewards",
            "Amount": 100000
          }
        }

So I've tried to change the "Item Type" to "Command" and "Plugin", however I'm still getting this error message.

Wondering if you could help point me in the right direction of getting this setup so I don't keep running into this issue.

FYI: The Item type of Item works just fine. Its only while I try to implement these Command bases items that i've having the issue.

Also, can you please explain to me what the ID key is compared to the Skin key? Can I just leave the first ID key a 0?

I'll have to check it out. Can you send me the complete item from the configuration?

Regarding the ID: it is an identifier that is used to index items to quickly find them. The ID must be unique among other items. Yes, it can be 0.

@BippyMiester Is the problem still relevant? Can I close this ticket?

Close it. Don't know if its still relevant as I no longer own any servers.  So I don't use the plugin.
