Whener I call the Simulator to run the 2nd time I get an assertion

[Couto]

i get this error 
I can give the code and more if you want please help me guys


Other question is how I put data in the content store

When the program breaks in gdb, use the backtrace ('bt') command to
inspect the call history that led to the assertion.

so I cant destroy here?

    Simulator::Stop(Seconds(20.0));

    Simulator::Run();
    Simulator::Destroy();

Here is an example that runs a simulation for a certain duration of time: 
https://gitlab.com/cttc-lena/nr-u/-/blob/master/examples/cttc-nr-wifi-interference.cc?ref_type=heads

Also, did u run the simulation under gdb as Tom suggested? Is that the full trace u get? 
./waf --run <program> --gdb"
once in gdb do :
run
once u get the assertion happens do:
backtrace

[Couto]

thanks for the example!
with bt i get this:

I need to change the prefix, thats my problem.

Can I get your discord or email or something?

[George Frangulea]

It tells you the line where this issue occurs /ndn-stack-helper.cpp, line=153 . 
Have you tried looking what happens in    StackHelper::Install(Ptr<Node> node). At first look it seems is a check to prevent installing NDN sack a 2nd time on that NodeId 0. 

Also try asking ChatGPT (openai.com). Just feed backtraces into it if you`re lazy reading them. Then feed that StakHelper code to help you understand what happens there. 

Definitely it has more time than anyone else has for work in August.
