Send a number in client to server error

[Kanglim12 (Capybara)]

hello devs
im currently making a script that get player friend’s id and send it to server, then make it as npc
but while sending id in client to server, error happens

heres my script

client

local Players = game:GetService("Players")
local PLR = Players.LocalPlayer
local CHAR = PLR.Character or PLR.CharacterAdded:Wait()

while true do
	wait(1)
	warn("repeat")
	local loc = script.Parent["Start Door"]
	warn("checking if Spawn1 is true")
	if loc.Spawn1.Value == true then
		local success, friendPages = pcall(function()
			return Players:GetFriendsAsync(PLR.UserId)
		end)

		if not success then
			warn("There was a error while getting player's friend id!")-- remember to handle pcall errors
			return
		end


		local function iterPageItems(pages)
			return coroutine.wrap(function()
				local pagenum = 1
				while true do
					for _, item in ipairs(pages:GetCurrentPage()) do
						coroutine.yield(item, pagenum)
					end
					if pages.IsFinished then
						break
					end
					pages:AdvanceToNextPageAsync()
					pagenum += 1
				end
			end)
		end

		local userIds = {}
		for item, _pageNo in iterPageItems(friendPages) do
			table.insert(userIds, item.Id)
		end
		local randomFriend = userIds[math.random(1, #userIds)]
		
		game.ReplicatedStorage.char:FireServer(Players ,CHAR, randomFriend)
		wait(20)
	end
	end

server

warn("is this even started")

game.ReplicatedStorage.char.OnServerEvent:Connect(function(Players, CHAR, randomFriend)
	
	print(randomFriend) -- in there, it prints my name not id

		warn("here?")


	local newFriend = Players:CreateHumanoidModelFromUserId(randomFriend)
		newFriend.Parent = CHAR
		newFriend:FindFirstChild("HumanoidRootPart").Anchored = false
		newFriend.Name = "Customer"

		warn("spawned")

		local NPClogic = script:WaitForChild("Move Script"):Clone()
		NPClogic.Parent = newFriend
		NPClogic.Enabled = true
end)

The first parameter to an OnServerEvent callback will always be the player that fired the event, it doesn’t look like you’re accounting for that here.
