Sidelink losses uplink EARFCN and bandwidth configuration when using ConstantSpectrumPropagation #21

I was running the example lte-sl-relay-cluster with the pathloss lteHelper->SetAttribute ("PathLossModel", StringValue (ns3::ConstantSpectrumPropagationLossModel"));

lteHelper->SetPathlossModelAttribute ("Loss", DoubleValue ());

Hello, I tried to reproduce this with the latest code in the default psc-4.0 branch. I made this modification:

diff --git a/src/lte/examples/d2d-examples/lte-sl-relay-cluster.cc b/src/lte/examples/d2d-examples/lte-sl-relay-cluster.cc

-  lteHelper->SetAttribute ("PathlossModel", StringValue ("ns3::Hybrid3gppPropagationLossModel"));
+  lteHelper->SetAttribute ("PathlossModel", StringValue ("ns3::ConstantSpectrumPropagationLossModel"));
+  lteHelper->SetPathlossModelAttribute ("Loss", DoubleValue ());

   //Enable Sidelink
   lteHelper->SetAttribute ("UseSidelink", BooleanValue (true));

and then I ran:

$ ./waf --run lte-sl-relay-cluster

and I did not see any error. Can you please clarify that you still experience this on the latest code, and if so, provide more hints as to how to reproduce?
