i installed the CS, and then the Json file into my Scala Server, under plugin for CS, and then Confg for Json.

when F1 "vanish" says i dont have permission in game chat...   https://ibb.co/tMt2zLY  however, when i try to give myself permission it says the file isnt there? what come i be doing wrong? i have Both Log, and console in Link

you need to give yourself the permmison.

In console do

oxide.grant user bushcake vanish.allow
(oxide.grant (user/group)  (name of group) (permisson)
Here are the other permissons for the plugin. 

• vanish.allow 
• vanish.unlock 
• vanish.damage 
• vanish.permanent 
• vanish.collision
