I’m trying to simulate nesting network at omnet++.
After i import the nesting project and inet into the omnet++, i build the project and i encounter some problems like below:

I have an error : Expression interfaceTable->findInterfaceByName(p.c_str()) returned nullptr at inet/linklayer/ieee8021as/Gptp.cc:83 — in module (inet::Gptp) Network.tsnSwitch1.gptp (id=133)
