ScenarioObject name cannot be Empty or None

[HLCaptain]

When trying to get objects from a Scenario, I always get the exception: beamngpy.logging.BNGValueError: Name cannot be empty or None!. On the map I loaded (east_coast_usa), some static objects does not have a name and validate_object_name throws an error while creating the ScenarioObject in python. I suspect, as the built-in world editor allows objects to have an Empty or None name, the python API should as well.

Hi,
can you please post the code that causes the error? The validate_object_name function is only called if the name is not None, so I'm not sure what's happening here.

Hi, problematic source code available here. You can start testing by running this file, then you should see some logs like this, after the level is loaded:

Could not load static instances from scenario: Name cannot be empty or None!

Keep in mind, that I use BNG_HOME environment variable to find the current BeamNG.tech program. Error occurs with BeamNGpy v1.28 and BeamNG.tech v0.31.3.0.

I suspect, that the name is not None, but empty and that raises the BNGValueError.

Hi, you're right and we will fix the bug in the next release of BeamNGpy. In the meantime, you can apply the patch to your copy of BeamNGpy by editing the beamngpy/scenario/scenario_object.py file as follows:

Thanks for the provided source code.

Fixed in BeamNGpy v1.29, thank you for reporting.
