Place teleport script erroring without an error message

Hello,
I’ve been working on a script to teleport a player to another player, which errors on line 28, but does not specify why.
This is the output:

Server Script:

-- bunch of locals before this
function joinUser(plr, destinationUser)
	print(destinationUser)
	local success, errorMessage = pcall(function()
		teleSuccess, teleErrorMessage, placeId, jobId = TeleportService:GetPlayerPlaceInstanceAsync(destinationUser)
	end)

	if success == false or teleSuccess == false then
		errevent:FireClient(plr)
		if errorMessage then
			print(errorMessage)
		end
		if teleErrorMessage then
			print(teleErrorMessage) -- line 28
		end
	else
		successevent:FireClient(plr)
		print(placeId,jobId,plr)
		TeleportService:TeleportToPlaceInstance(placeId, jobId, plr)
	end
end

send.OnServerEvent:Connect(joinUser)

Local script:

-- bunch of locals and gui code
enterbt.MouseButton1Click:Connect(function()
	local success, error = pcall(function()
		game:GetService("Players"):GetUserIdFromNameAsync(userbox.Text)
	end)
	if success == true then
		print(game:GetService("Players"):GetUserIdFromNameAsync(tostring(userbox.Text)))
		send:FireServer(game:GetService("Players"):GetUserIdFromNameAsync(userbox.Text))
	else
		print(error)
		enterbt.Text = "Error!"
		wait(3)
		enterbt.Text = "Join"
	end
end)

The error on line 28 might occur if TeleportService:GetPlayerPlaceInstanceAsync(destinationUser) fails to return a value for either teleSuccess or teleErrorMessage , making them both nil . This would then cause an error when trying to print teleErrorMessage .

To avoid this error, you could add a check to see if teleErrorMessage is not nil before printing it. Here’s an updated version of your code that includes this check:

function joinUser(plr, destinationUser)
	print(destinationUser)
	local success, errorMessage = pcall(function()
		teleSuccess, teleErrorMessage, placeId, jobId = TeleportService:GetPlayerPlaceInstanceAsync(destinationUser)
	end)

	if success == false or teleSuccess == false then
		errevent:FireClient(plr)
		if errorMessage then
			print(errorMessage)
		end
		if teleErrorMessage then
			print(teleErrorMessage)
		end
	else
		successevent:FireClient(plr)
		print(placeId,jobId,plr)
		TeleportService:TeleportToPlaceInstance(placeId, jobId, plr)
	end
end

Note that I also added a check for errorMessage before printing it to avoid a similar error in case it is nil .

I’ve just removed the check if teleSuccess is false and the check for teleErrorMessage and it seems to work, I don’t know what GetPlayerPlaceInstanceAsync did for the teleSuccess to be false and teleErrorMessage to be "", but I’m not complaining that it works now. Thank you for your help!
