bad argument #3 to 'Text' (string expected, got Object) ?

bad argument #3 to 'Text' (string expected, got Object) ? issue is in server script

Local Script :

local player = game.Players.LocalPlayer
script.Parent.MouseButton1Click:Connect(function()
		  game.ReplicatedStorage.msg:FireServer(script.Parent.Parent.TextBox.Text)
end)
script.Parent.Parent.TextBox.FocusLost:Connect(function(enterPressed)
		  game.ReplicatedStorage.msg:FireServer(script.Parent.Parent.TextBox.Text)
end)

Server Script :

			wait(3)
			game.Lighting.Msg:Clone().Parent =script.Parent.Head
			function fs1(text)
script.Parent.Head.Msg.Image.Texter.Text = text
end
game.ReplicatedStorage.msg.OnServerEvent:Connect(fs1)

The first parameter of OnServerEvent is always the player that fired the remote. Therefore, you just need to add it to your function's arguments.

wait(3)
game.Lighting.Msg:Clone().Parent =script.Parent.Head

function fs1(player, text)
	script.Parent.Head.Msg.Image.Texter.Text = text
end

game.ReplicatedStorage.msg.OnServerEvent:Connect(fs1)
