Concerning Engine Error Message "exception while signaling: Must be a LuaSourceContainer"

[MuffinHandler]

Hi I reported this issue before. However I could not isolate it, so it might have been challenging to review the bug. This time around I isolated the bug and made a .rbxl bug repro file.

Internal Error Message "exception while signaling: Must be a LuaSourceContainer”"

I am getting the “exception while signaling: Must be a LuaSourceContainer” error for cloning an object. I did some tests and apparently it is triggered at the line I clone the object again. here: local new = a:clone() local a = script.Parent.Parent:FindFirstChild("2Cart"):clone() local deb = false local rides = workspace:WaitForChild("Rides") function chng() if deb == true then return end deb = true local new = a:clone() new.Parent = rides new:MakeJoints() --for i,v in pairs(new:GetDesce…

The bug/error message gets triggered whenever a model with a script is cloned.

local main = workspace:WaitForChild("Model")
local cloneReference = main:Clone()
main:Destroy()

function CloneModel()
	local newCloneReference = cloneReference:Clone()
	newCloneReference.Parent = workspace
end

while true do
	task.wait(0.1)
	CloneModel() -- errors: "exception while signaling: Must be a LuaSourceContainer"
end

Why are you making a duplicate report? Edit your original report and bump it if needed.
