i am making an admin panel with server joining but i keep getting the error Cannot teleport to empty instance id. Aborting teleport.

it takes the textvalue of a textbox where you input a job id, which when its valid still returns that error

hierarchy:

local jobId = game.JobId

local tpService = game:GetService("TeleportService")

local joinJobId = script.Parent.Parent.Parent.jobId.Job.Text

local text = script.Parent

print("jobId: " .. jobId)

text.Text = jobId

local joinButton = script.Parent.Parent.Parent.joinJobId.Join

joinButton.MouseButton1Click:Connect(function()
    print(joinJobId)
    tpService:TeleportToPlaceInstance(game.PlaceId, joinJobId)
end)
