Trouble Running Tutorial 3

[KorelU]

Describe the bug
I’ve been looking at Tutorials 3 from the Documentation which address mobility. Unfortunately, I am having trouble running the examples from Tutorial 3. The Running with XML file using NS2 Movement seems to throw an error when I follow the Documentations examples.

To Reproduce
Steps to reproduce the behavior:

1. Launch Oracle VM Virtual Box with Ubuntu 22.04.3LTS installed
2. Run sudop core-daemon on a new terminal
3. Run core-gui on a new terminal
4. Given a new interface go to file open and find directory "home/vboxuser/Documents/core/package/examples/turorials/tutorial3/scenario.xml"
5. Click Start Session on the upper left corner
6. Click Run on wLan3 Mobility Player
7. New window opens saying GRPC Exception: Mobility Error "exception calling applicaiton: int() argument must be a string, a bytes-like obj ect or a real, number not a 'NoneType"

Expected behavior
Observe movement of the nodes

Thanks for helping point this out, paths for referenced files in the scenario are corrected on the develop branch for a develop install. Ready for the next release.

You could manually adjust the scenario.xml file to point to the right path to correct your issue.
