Server_reward shop

I have added this plugin to my server reward shop and cannot figure out for the life of me how to ssale it lol this is the command i was trying to use "bpset %STEAMID% 3"

"kits": {},
"commands": {
"BackPack x2 Rows": {
"description": "BackPack x2 rows",
"iconName": null,
"commands": [
"bpupgrade $player.id"
],
"displayName": null,
"cost": 2500,
"cooldown": 0

I have tried for about an hour to get this in mt rewards store, but no luck can anyone see what ive done wrong?

{
  "items": {},
  "kits": {},
  "commands":{
    "BackPack x2 Rows":{
    "description":"BackPack x2 rows",  
    "iconName": null,
    "commands": [
    "bpupgrade $player.id"
    ],
    "displayName": null,
    "cost": 2500,
    "cooldown": 0
