After an hour of troubleshooting I still can't get this escape pod script to work. Why?

I made a game sort of like Innovation Inc Spaceship.

I want to make it so that the Pod Endings are possible. I can get as far as getting the names of players inside of pods, but how exactly do I teleport them to another place? Here's my code so far.

if pod.Name == "Pod" then


		local pfft = planets -- planets is set earlier as the place id of the target planet
		print("Test Successful on first stage")
		for lol, seat in pairs(pod:GetChildren()) do
			if seat.Name == "Seat" then
				print("Test Successful on second stage")
				local weld = seat:FindFirstChild("SeatWeld")
				if weld then
					print("Test Successful on third stage")
					local humanoidroot = weld.Part1
					local playerName = humanoidroot.Parent.Name
					print(playerName)
					print(humanoidroot)
						-- Get player from characte
							-- Teleport the player
							TeleportToPlaceInstance(pfft, playerName)
							print("Test Successful on final stage")
				end
			end
		end
	end

It just complains about "calling null".
