Closed [Modding Lua API] entity.getOutboundNodeIds() returns empty table.

Hey, I already asked this in the Modding Help, but I believe this is an issue so I will report this here:
Version: Unstable - Glad Giraffe Update 3
Test code:

Code:

function onInteraction(args)
  local connectedIds = entity.getOutboundNodeIds(0) -- 0 is the node index
  world.logInfo(#connectedIds) -- Returns 0 if any lamp or something is connected (its obvious that it should be a higher value)

  for k,v in ipairs(connectedIds) do
    world.logInfo("Index: "..k.." - EntityId: "..v)
  end -- this one does nothing, because the table is empty
end

I added comments so you should see where the problem relies on.
Hope you can either tell me an alternative, but I don't think there is another one, or address this as a bug and it will be fixed in one of the future updates.
