I got this to work on my local test system, not working live system.
From Jail config
"prisons": {
"prison": {
"zoneId": "jail",
"spawnFile": "prison",
"inmateKit": "jail",

From Kit config
"jail": {
"name": "jail",
"description": null,
"max": 0,
"cooldown": 0.0,
"authlevel": 0,
"hide": false,
"npconly": false,
"permission": null,
"image": null,
"building": null,

Do I need to wipe the prison "/jail" and start new

As always Thanks in advance!
