I think a better fix would be to use the following just after the client.Do(req) on line 48:

if resp != nil {
   defer resp.Body.Close()
}

bonus for catching the error in an anon func and logging it ...

defer func() {
  if err := rest.Body.Close(); err != nil {
    log-error-here
  }()

our coverage for errors in this registry option isn't great but this should solve a potential resource leak.
