How can I fix this script about making a custom team with Filtering Enabled?

I tried to make a script by making a team with a custom name by typing the name and pressing a button on a GUI with FE, as I am learning about RemoteEvents, but when I tried assigning a team to the player I got this error:

13:32:43.078 - ServerScriptService.MakeTeam:7: bad argument #2 to '?' (string expected, got Object)

Here are the scripts

Local Script on the Button:

local button = script.Parent
local box = script.Parent.Parent.TeamName

button.MouseButton1Click:Connect(function()
	game.ReplicatedStorage.Events.MakeTeam:FireServer(box.Text)
end)

Script on ServerScriptService

game.ReplicatedStorage.Events.MakeTeam.OnServerEvent:Connect(function(player, teamName)
	local team = Instance.new("Team")
	team.Parent = game:GetService("Teams")
	team.Name = teamName
	team.TeamColor = BrickColor.Random()
	
	game:GetService("Players")[player].Neutral = false	
	game:GetService("Players")[player].Team = team.Name
end)

So what that error means is that coded wanted a string like example "ThisIsString" but instead it got object which is like a table I think

So what I suggest you do is before the :FireServer(box.Text) add print(box.Text) to see if it is a string

And before local team = Instance.new("Team") code add print("What is player name"..player.Name) print("What is team name"..teamName)

That is to see what those 2 parameters is and if teamName is a string.
