Checking if a user has the police job when running a chat command

[Dazzah]

So hi, im trying to work out how i would make a command only available for users with the Police job, ive done alot of googling and scouring but i carnt seem to find anything which works for my case, ive tried adding it directly to the function which is ran when the command is ran, but it didnt work nor when i added it to the Event Handler. The function id like to add it to is

function giveWeapon(hash)
GiveWeaponToPed(GetPlayerPed(-1), GetHashKey(hash), 100, false, true)
end

any help would be greatly appriciated, im not the best with lua so some visual examples, code examples would be greatly appreciated! Thank you.

Make a command, and make a line stating

if xPlayer.job.name == police then
giveweapon()
else
Citizen.Wait(0)
end

This is the command for unracking weapons, is there anything i need to predefine etc or no?

AddEventHandler('unrack', function(userName, args)
    local player = GetPlayerPed(-1)
    if RequireInVehicleToUnrack == true then
        if IsPedInAnyVehicle(player, true) then
            if args[1] == "1" and weaponTaken == false then
                GiveAR(userName)
            elseif args[1] == "2" and weaponTaken == false then
                giveShotgun(userName)
            elseif args[1] == nil and weaponTaken == false  then
                notify("~r~Please specify a weapon type. /unrack 1 or 2 (1 = Carbine Rifle, 2 = Shotgun)")
            elseif weaponTaken == true then
                notify("~r~You already have a weapon unracked.")
            end
        else
            notify('~r~You must be in a vehicle to unrack your weapon.')
        end
    else
        if args[1] == "1" and weaponTaken == false then
            giveShotgun(userName)
        elseif args[1] == nil and weaponTaken == false  then
            notify("~r~Please specify a weapon type. /unrack 1 or 2 (1 = Carbine Rifle, 2 = Shotgun)")
        elseif weaponTaken == true then
            notify("~r~You already have a weapon unracked.")
        end
    end
end)

This is the error im getting when i have it checking if the user is police like this

RegisterCommand("loadout", function ()
	if xPlayer.job.name == police then
		RemoveAllPedWeapons(GetPlayerPed(-1), true)
		giveWeapon("weapon_combatpistol")
		weaponComponent("weapon_combatpistol", "COMPONENT_AT_PI_FLSH")
		giveWeapon("weapon_flashlight")
		giveWeapon("weapon_nightstick")
		giveWeapon("weapon_stungun")
		AddArmourToPed(GetPlayerPed(-1), 100)
		notify("~b~Police loadout has been loaded.")
		notify("~r~To receive a rifle or shotgun, you must type /unrack by a police vehicle.")
	else
		notify("~b~You are not Police.")
		Citizen.Wait(0)
	end 
end)

at the top of the script’s client lua file add ESX = nil

And before the if add the following:
local _source = source
local xPlayer = ESX.GetPlayerFromId(_source)

@Th3Cha0s

I now get this error

i assume because i havent defined esx?
