exportToOpenStudio not generating CSV results file


I am running an energy simulation (based on this tutorial from Chris: Hydra Viewer)

But there is an issue with exportToOpenStudio - the CSV results file is not generated, so readEPResult throws an error:

I am using Openstudio Version 3.2.1, and Honeybee-Legacy Version 0.0.66.

Is there an issue with my setup, or is this a known error?
