Error running "Create Baseline Building" Measure in OS 2.3+

savecancel

I am having trouble executing the "Create Baseline Building" measure on a number of OpenStudio models in versions 2.3 and 2.4. Previous iterations of these models (e.g., based on OS version 1.14) seemed to execute the "Create Baseline Building" measure just fine. I have tried differeing Building Types (e.g., Small, Medium, Large Office) and different Standards (2007, 2010, and 2013) without any luck.

An example of the error message I receive is as follows:
