Why does my module script always return true?

Right, so I'm trying to make swords here. As you can see from the title, I'm using module scripts to deal with all the logic or whatever. Now, I have a region3 defined in my module script, and if a player is in that region3 I want them not to take damage. Now, CFrames, Region3s, all that kind of stuff has always been a weak side to me, so I found online some code for that and I modified it a bit to match what I wanted. Now with that, I tested the thing on a local server and whether I was in the region or not it would still kill the player. I need help with that, thanks.

This is my function inside of the module script:

function module.onTouchDamage(h)
	local afkregion = Region3.new(game.Workspace.afkregion1.Position, game.Workspace.afkregion2.Position)
	local isPlayerInRegion
	
	if h.Parent:FindFirstChild("Humanoid") then
	
		local char = h.Parent 
		local whitelist = char:GetChildren()
		----------------------------------------
	
		local partsInRegion = game.Workspace:FindPartsInRegion3WithWhiteList(afkregion, whitelist)
		
		if #partsInRegion >= 1 then
			
			isPlayerInRegion = true
			print(#partsInRegion)
			print(partsInRegion[1].Name)
		
		else
			
			isPlayerInRegion = false
			
		end
	
		----------------------------------------
		
		if isPlayerInRegion == false and char:WaitForChild("CanTakeDamage").Value == true then
			
			return true		
			
		else
			
			return false
				
		end	
	end	
end

This is a part my of script inside the sword.

sword.Touched:Connect(function(h)
	
	if h.Parent:FindFirstChild("Humanoid")  then
		
		local char = h.Parent
		local player = sword.Parent.Parent.Parent --Ik i used 4 parents in a row but you get it
		
		if char.Name ~= player.Name then
			
			local doDamage = module.onTouchDamage(h)
		
			print(doDamage)
		
			if doDamage == true then
			
				char.Humanoid:TakeDamage(dmg.Value)
			
			end
		end
	end	
end)

All variables are defined
