Looks like an error on daylighting, We will look into it.

[12:27:16.505274 ERROR] [openstudio.model.ThermalZone] Fraction of Zone Controlled by Primary Daylight Control is 0.5632 and you supplied a Secondary Fraction of 0.4368 which would result in a sum greater than 1.0 [12:27:16.505316 ERROR] [openstudio.model.ThermalZone] Fraction of Zone Controlled by Primary Daylight Control is 0.572324 and you supplied a Secondary Fraction of 0.427676 which would result in a sum greater than 1.0 ...

Looks like a bug, probably due to a rounding mistake in the primary & secondary daylight sensor control fraction adding up to more than 1, which EnergyPlus treats as an error, which causes the sizing run to fail and thus causes the model generation to fail. I've filed a bug and will update this answer once the bug is fixed. Should be done for the OpenStudio 2.5.0 major release in March, if not sooner.
