I have a piece of code where i evaluate to drop vertices but only if a pre-fetch of
g.V().<filters>.hasNext() returns true.

Problem is on my subsequent call to fetch the nodes themselves it is getting stuck for some reason.

hasNext, err := g.V().<filter>.hasNext()

if err != nil {
  return err 
}

if hasNext {

   // Program is stuck here
   ids, err := g.V().<filter>.Id().ToList()
   ....
}
