This is due to the InvokeServer method returning nil. Can you provide server sided code?

  local Rep = game.ReplicatedStorage
local ToolData = require(Rep.ToolData)
local Debounce = {}
local MPS = game:GetService("MarketplaceService")

Rep.TriggerTool.OnServerEvent:Connect(function(Player)
	if Player and Player.Character then

	end
end

That is the whole server-side script

So it looks like it’s returning nil because of none of the primary if statements checks are being met. For debugging purposes, print each value the if statement checks and then proceed from there.

That shouldn’t happen because I only was working client side and everything from the server side was working properly.

Sometimes code breaks. All I can say is there doesn’t appear to be any other way this could return nil since each of your statements incorporates a return. I suggest proceeding with my debug solution.
