[ndnSIM] Question about Forwarding of interest

Hi all,

I want to do one hop forwarding of Interest Packet. I'm trying to get the
HopCount value in the following manner in the
*Forwarder::onIncomingInterest *function so that I can further manipulate
it for one hop forwarding of Interest but in output I'm just getting *Log:
Hop count: *


int hopCount = 0;

  auto hopCountTag = interest.getTag<lp::HopCountTag>();
  if (hopCountTag != nullptr) {
    hopCount = *hopCountTag;
  LogManager::AddLog("Hop count: ", hopCount);

Log: Hop count:

Do you have any idea about the cause or may be the solution regarding how
should I pursue it to get the required output?
