Attempt to call a nil value

Output say attempt to call a nil value. Shared is created like this. If anything, these are excerpts of scripts.

	if shared.is_banned_in_team(Player, TEAM) then -- Output says about this line
		script.Parent.TextScaled = false
		script.Parent.TextSize = 25
		script.Parent.Text = "Фракция заблокирована за нарушение."
		return
	end

	elseif state == "Transfer" and MyModel:WaitForChild("DetainESF") then
		shared.ban_in_team(CurrentPlayer, CurrentPlayer.Team)
		CurrentPlayer.Team = game:GetService("Teams")["Test Subject"]
		CurrentPlayer:LoadCharacter()

This means the function shared.is_banned_in_team you’re attempting to call is nil. Check the code above to see If you correctly declared the function.

I haven’t changed much, but it still doesn’t work. Below I will attach all the scripts related to shared.

local bans_default = {}
local ban_info = {}


local function shallow_copy(original)
	local copy = {}

	for key, value in pairs(original) do
		copy[key] = value
	end

	return copy
end


for _, Teamq in pairs(game.Teams:GetChildren()) do
	bans_default[Teamq.Name] = false
end


shared.ban_in_team = function(Player: Player, Teamq: Team) : nil
	ban_info[Player.UserId][Teamq.Name] = true
end


shared.is_banned_in_team = function(Player: Player, Teamq: Team) : boolean
	print(ban_info)
	return ban_info[Player.UserId][Teamq.Name]
end


game.Players.PlayerAdded:Connect(function(player: Player)
	ban_info[player.UserId] = shallow_copy(bans_default)
end)

	if shared.ban_in_team(Player, Teamq) then
		script.Parent.TextScaled = false
		script.Parent.TextSize = 25
		script.Parent.Text = "Фракция заблокирована за нарушение."
		return
	end

	elseif state == "Transfer" and MyModel:WaitForChild("DetainESF") then
		shared.ban_in_team(CurrentPlayer, CurrentPlayer.Team)
		CurrentPlayer.Team = game:GetService("Teams")["Test Subject"]
		CurrentPlayer:LoadCharacter()
	end

Can you provide where exactly is nil being called

#5

if shared.ban_in_team(Player, Teamq) then

#6

You are not returning any value from the function shared.ban_in_team … thus it returns nil

#7

The error you’re getting mainly occurs when you are trying to call a function that does not exist OR when calling a function with a nil variable. Did you check that both variables Player and TEAM are not nil?
