Unable to cast value to object? [Solved]

This error just recently appeared and I have no idea what it means. The error is on line 10. Note; script.Parent is not the workspace. I'm putting the bleft and tright parts inside the scripts parent as I will use a different position of bleft and tright for every copy of the script's parent.

Server script:

local bleft = script.Parent.bleft.Position
local tright = script.Parent.tright.Position

local region = Region3.new(
	Vector3.new(math.min(bleft.X, tright.X), math.min(bleft.Y, tright.Y), math.min(bleft.Z, tright.Z)),
	Vector3.new(math.max(bleft.X, tright.X), math.max(bleft.Y, tright.Y), math.max(bleft.Z, tright.Z))
) -- math.min & max to prevent issues with Region3

while wait() do
	for i, part in pairs(workspace:FindPartsInRegion3WithIgnoreList(region, {bleft, tright, script.Parent})) do
		local player = game.Players:GetPlayerFromCharacter(part.Parent)
		
		if player then
			if not player.Transfurmed.Value then -- If player is not transfurmed
				print('Initiate transfurmation')
				
				player.Transfurmed.Value = true -- To clarify that player is transfurmed to not initiate transfurmation on a transfurmed player
				game.ReplicatedStorage.GiveAbilityToTransfurm:FireClient(player)
				
				player.Character.Shirt:Destroy()
				player.Character.Pants:Destroy() -- To turn whole character to color
			end
		end
	end
end

Nevermind, I forgot i set the bleft and tright to their respective positions, not the objects themselves.

The solution here is to reference them indiviually.
