How do I attach a new rope cronstraint to a tool handle?

So I was trying to make a fishing simulator game. I tried making it so a rope appeared when I clicked with a tool, it all worked well until I got to the rope instance part of the code, it does not attach to my handle and it doesn't even appear in my world, this is my code:

tool = script.Parent

handle = tool:WaitForChild("Handle")

tool.Activated:Connect(function()
    local newRope = Instance.new("RopeConstraint",game.StarterPack["Basic rod"])
    newRope.Attachment0 = handle
    print("Hello world!")
end)

and this is my error messages:

13:06:05.416 Expected Attachment got Tool for RopeConstraint:Attachment0. - Server - Script:7

13:06:05.416 Stack Begin - Studio

13:06:05.417 Script 'Players.Anderssc.Backpack.Basic rod.Script', Line 7 - Studio - Script:7

13:06:05.417 Stack End - Studio

Please help me so that I can keep on going
