std::logic_error when adding an RSU #196

Closed OverwatchGirl closed 3 years ago

OverwatchGirl commented 3 years ago

Hello @riebl

I'm trying to run a basic scenario, with a bidirectional way, two flows and two RSUs, but when running the scenario, i get this error : std::logic_error: basic_string::_M_construct null not valid -- in module (artery::StationaryMiddleware) World.rsu[0].middleware (id=23), during network initialization

Thank you in advance.

Can you give me some more details how to reproduce this error? Have you modified some Artery sources or does this happen with the unmodified Artery source code as published on GitHub?

Yep, it happens with it as long , as i add rsu to a very basic scenario, one road and two flows.

Can you run your setup with a debugger attached to see at which line the std::logic_error exception is thrown? When I run the rsu_grid scenario, which features several RSUs equipped with StationaryMiddleware and RsuCaService, no exceptions are thrown. I don't know what is different in your scenario compared to rsu_grid that causes this error.

I think that my xml files weren't well written, because when i created a new project and with new xml files (.rou, .net and services) it worked just fine.

thank you for your time.
