when I call GetPlayerPlaceInstanceAsync nothing happens?

I have the following localscript inside a follow friend button

local res = script.Parent.Parent:WaitForChild("result")
local foll= script.Parent.Parent.PName
local id
local teleportService = game:GetService("TeleportService")


script.Parent.MouseButton1Down:connect(function()
    if deb then
        deb = false
        id = game.ReplicatedFirst.FollowFriend:InvokeServer(foll.Text)
        if (id) then
            teleportService:TeleportToPlaceInstance(570934982, id, p)
        else
        res.Text = "Could not teleport: server might be full or player is not playing"
        wait(.2)
        deb = true
        end
    end
end)

which calls this remote function inside a server script

local event = game.ReplicatedFirst.FollowFriend
players = game.Players
local teleportService = game:GetService("TeleportService")

function event.OnServerInvoke(player,following)
    local id = players:GetUserIdFromNameAsync(following)
    if id and id>0 then
        local success, errorMsg, placeId, instanceId = teleportService:GetPlayerPlaceInstanceAsync(id)
        if success and (570934982==placeId) then
            return instanceId
        else
            return false
        end
    else
        return false
    end
end

When I test it offline I get "GetPlayerInstanceAsync" needs to be called from the server, when I test it online, the code does not run, no matter what I do the code inside the remote function does not work. I tried adding some print("stuff") to see where it breaks but those don't run either. Any idea what's wrong?
