How do I fix attempt to index nil with 'GetChatForUserAsync'?

I'm trying to make a filter for my custom chat but every time I try to filter something it throws an error.

--LocalScript that send the message to the server

local LocalPlayerName = game:GetService("Players").LocalPlayer.Name
local Rank = "(Test Rank)"
local Text = "im trying to filter this: d7sjfix8snd" --text

game:GetService("ReplicatedStorage").SendMessage:FireServer(LocalPlayerName,Rank,Text)

The script above and below work fine

--Script that receives the message

game:GetService("ReplicatedStorage").SendMessage.OnServerEvent:Connect(function(PlrWhoSent,Plr,Rank,Message)
	local TextService = game:GetService("TextService")
	local Msg = ""
	local success,err = pcall(function()
		FilteredString = TextService:FilterStringAsync(Message,PlrWhoSent.UserId)
	end)
	if err then
		warn("Failed to filter text: "..err)
		Msg = "<Failed To Filter Text>"
	else
		Msg = FilteredString
	end
	
	game:GetService("ReplicatedStorage").SendMessage:FireAllClients(Plr,Rank,Msg)
end)

This is where the error occurs

--LocalScript that receives the message

game:GetService("ReplicatedStorage").SendMessage.OnClientEvent:Connect(function(Plr,Rank,Msg)
local FilteredMessage = Msg:GetChatForUserAsync(game:GetService("Players").LocalPlayer.UserId) 
	
	--[[script.Parent.MessageReady:Fire(FilteredMessage)

	This sends it to the script that handles the messages]]

I tried looking for a solution, but i didnt find anything.

I think i fixed it!

Server script:

--Script that receives the message

game:GetService("ReplicatedStorage").SendMessage.OnServerEvent:Connect(function(PlrWhoSent,Plr,Rank,Message)
    local TextService = game:GetService("TextService")
    local Msg = ""
    local success,err = pcall(function()
        FilteredString = TextService:FilterStringAsync(Message,PlrWhoSent.UserId)
    end)
    if err then
        warn("Failed to filter text: "..err)
        Msg = "<Failed To Filter Text>"
    else
        Msg = FilteredString
    end
	local FilteredMsg = Msg:GetChatForUserAsync(PlrWhoSent.UserId)
	game:GetService("ReplicatedStorage").SendMessage:FireAllClients(Plr,Rank,FilteredMsg)
end)

Client script:

--LocalScript that send the message to the server

local LocalPlayerName = game:GetService("Players").LocalPlayer.Name
local Rank = "(Test Rank)"
local Text = "im trying to filter this: d7sjfix8snd" --text

game:GetService("ReplicatedStorage").SendMessage:FireServer(LocalPlayerName,Rank,Text)

game:GetService("ReplicatedStorage").SendMessage.OnClientEvent:Connect(function(Plr,Rank,Msg)
warn(Msg)
end)
