Roblox Empty Group Finder

Question

local group = game:GetService("GroupService")
local id = 0
game.Players.PlayerAdded:Connect(function(plr)
    wait(2)
    while wait(0.01) do
        local stop = false
        id += 1
    local info = 0
        if stop == false then
            if  group:GetGroupInfoAsync(id) then
                    local info = group:GetGroupInfoAsync(id)
                    print(info)
                    if info["Owner"] then
                    local owner = info["Owner"]["Name"]
                    local id = info["Id"]
                    if owner then
                        local name = info["Name"]
                        local result = name.." (ID: "..id..") is owned by "..owner.."!"
                        print(result)
                        plr.PlayerGui.ScreenGui.TextLabel.Text = result
                    end
                elseif info["Owner"] == nil then
                    plr.PlayerGui.ScreenGui.TextLabel.Text = "Group found! ID: "..id
                    while true do
                        wait()
                        stop = true
                end
                end
            else
                id += 1
            end
        end
    end
end)

It works but it stops because http://roblox.com/groups/12 isn't a valid group. I want it to pass that and add to the id. How do I do it? Error: GroupService:GetGroupInfoAsync() failed because HTTP 404 (Not Found)

You can use LUA's very handy pcall function to catch errors.

Here is a guide on the Roblox DevForum on how to use them :)
