The issue is that your model does not contain design day objects. If the model does not include design days, then the .osm to .idf translator does not create zone sizing objects which contain the reference to the design specification outdoor air objects for your zones.
I've updated the measure on BCL to throw an error when design days are missing before it checks the zone sizing objects for the design specification outdoor air.
