ERROR MosaicStarter - Stopping simulation due to a critical error. org.eclipse.mosaic.rti.api.InternalFederateException: Error code: 0x01000013: There was an error during an advance time.

[pv2-0]

Hello,

I have a simulation with 2 vehicle applications, 1 server application and a roadside unit application that was working on Mosaic 20.0.
I recompiled all of the applications using version 23.0-SNAPSHOT and made a few small edits to match the updated class names. I have been stuck getting the error message below. I compared my applications with the corresponding example applications (e.g my ServerApp with the WeatherServerApp in the tutorials) and matched up the "extends" and "implements" sections at the top. I also skimmed the rest of the applications for significant differences and could not find any. From what I understand, this message means that the MosaicStarter class is found, but not usable in my applications. Is this right? None of the files that I created are mentioned in the stack trace. Do you have any suggestions for where else to look for what is causing this issue?

Thank you.

This error usually is thrown if you try to map an application on a unit with a different type. This means the apps you map on your vehicles have to extend AbstractApplication<VehicleOperatingSystem, your RSU AbstractApplication<RoadSideUnitOperatingSysten, and so on.

Are you potentially trying to map the same applications on your server and your RSU?

Yes, it turns out I was using my server app for some of my roadside units. I removed those in the mapping file and that fixed it. Thank you!

You're welcome!
