Investigate into why when creating a new material for a newly added object the exporter can't find it #11

How was this solved? I can't seem to get even the most basic export functionality to work (i.e. exporting the default cube as CityJSON). I have the same issue as here: https://blenderartists.org/t/export-to-json/1327958

So I face the following error:

Python: Traceback (most recent call last):
