How to stop and destroy Dialog?

I have some blocks, that you can speak with they, and if you select a specific choice, the block must be destroy, I make an understandable extract of the code

LOCAL SCRIPT:

NOTE: this is a Local Script of a tool

local dialog = tool:WaitForChild("MaterialsDialog") --the dialog
local clonedDialog --a variable to clone the dialog
--this is the function to use the dialog
--and acctualy, this only call the server, and send the object
local function choiceFunction(choice, object)
	if tostring(choice) == "Yes" then
		exchangeWoodForMaterials:InvokeServer(object)
	end
end
local function onEquip()
	--NOTE: the getPlayerStuff:InvokeServer(), give the array of objects
	for _, object in ipairs(getPlayerStuff:InvokeServer()) do
		if object.Name == "PlainTable" then
			--clone the dialog
			clonedDialog = dialog:Clone()
			--set the dialog to the object
			clonedDialog.Parent = object
			--set the interface to the dialog
			clonedDialog.DialogChoiceSelected:connect(
				function(_, choice) 	
					choiceFunction(choice, object) 
				end)
		end
	end
end

SERVER SCRIPT

local exchangeWoodForMaterials = --new RemoteFunction
function exchangeWoodForMaterials.OnServerInvoke(player, object)
	--get the price of the object
	local price = buildingMotor:GetPrice(object.Name)
	--give the player the price
	managerDataStorage:ChangeStat(player, "Materials", price) 
	object:Destroy() --destroy the object
end

and, I got this error:

partOrCharacter must be in the Workspace

Stack Begin

Script 'CoreGui.RobloxGui.CoreScripts/MainBotChatScript2', Line 304 - upvalue chatFunc

Script 'CoreGui.RobloxGui.CoreScripts/MainBotChatScript2', Line 323 - global selectChoice

Script 'CoreGui.RobloxGui.CoreScripts/MainBotChatScript2', Line 348

Stack End

I need to stop the Dialog or destroy, acctualy, the Dialog it's going to be destroy anyway.

Any help will be appreciated.
