I'm trying to make a skyblock in which the improvements of the island are unlocked with money, but when I enter the command that through npc it will go to console ie "/ lpb user %player% permission set askyblock.island.range.150" or something like that instead of% player% I tried with "@p" etc but it turns out that the command doesn't exist, is there any way to do it?

Citizens is a Spigot plugin, therefore handling commands on the Spigot server/Console.
/lpb is the command of LuckPerms Bungee, a BungeeCord plugin.
BungeeCord and Spigot are two completely separate things and won't interact with each other, except for some really specific cases.
Just use the Spigot version of LP and use /lp instead of /lpb
In addition is it not LPs job to translate placeholders in commands, that would be Citizens job.
