?Vector3 is confused on behavior

Hello. I'm trying to make an auto death teleporter but it's not working. It says Vector3 is not a valid member of Part and it just won't work.

local plr = game.Players.iiDkOffical
local character = plr.Character
character:WaitForChild("Humanoid").Died:Connect(function()
	local pos1 = character.HumanoidRootPart.Position
	plr:LoadCharacter()
	wait(0.11)
	character.HumanoidRootPart.Vector3 = Vector3.new(pos1)
end)

you can't do HumanoidRootPart.Vector3.. I think you meant to do HumanoidRootPart.Position, which returns a Vector3

The property for the position is Position, as you had it on line 4.

To make it work for all players, I would do it like this.

local Players = game:GetService("Players")

Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		local connection
		connection = character.Humanoid.Died:Connect(function()
			local last_cf = character:GetPrimaryPartCFrame()
			player:LoadCharacter()
			wait(0.1)
			character:SetPrimaryPartCFrame(last_cf)
			connection:Disconnect()
		end)
	end)
end)

This also accounts for rotation. I also disconnect the connection when I am finished, to avoid a memory leak. A new connection will be remade, but only when they respawn.

replace line 7 with character.HumanoidRootPart.Position = Vector3.new(pos1)
