Player removing event which sends message to client and back not working?

So I have a pet game, which after a player leaves, makes a table of the players pets. The pets are then saved. The problem is that the message never reaches the client. Here is my server script:

   local rs = game:GetService("ReplicatedStorage")

local event = rs:WaitForChild("PlayerRemoveClient")

local event2 = rs:WaitForChild("PlayerRemoveServer")

  

game.Players.PlayerRemoving:Connect(function(plr)

print("bye")

event:FireClient(plr)

end)

event2.OnServerEvent:Connect(function(plr, t)

print(unpack(t));

  

end)

Here is my local script:

    local rs = game:GetService("ReplicatedStorage")

local event = rs:WaitForChild("PlayerRemoveClient")

local event2 = rs:WaitForChild("PlayerRemoveServer")

  

event.OnClientEvent:Connect(function()

print("hi")

local t = {}

for i,v in pairs(script.Parent:GetChildren()) do

if v:IsA("ViewportFrame") and v.Name ~= "ZZ" then

table.insert(t, v.Name)

end

end

  

event2:FireServer(t)

end)
