Have you followed the advice in the error message?
Error: attempting to enable the packet metadata subsystem too late in the
simulation, which is not allowed.
A common cause for this problem is to enable ASCII tracing after sending
any packets. *One way to fix this problem is to call
ns3::PacketMetadata::Enable () near the beginning of the program*, before
any packets are sent.
