Why is my eplusout error file empty?

I am running OpenStudio SDK version 3.7.0 with the associated SketchUp Plugin, and I am running into an error when running the EnergyPlus Simulation. Despite all spaces being enclosed, I receive the following errors: In addition, the Energyplus eplusout.err log is completely empty. Why am I unable to get an EnergyPlus error log output? I have checked my geometry a lot, and it seems like everything is connected as it should.

[14:43:44.655761 FATAL] [openstudio.workflow.OSWorkflow] EnergyPlus Terminated with a Fatal Error. Check eplusout.err log.

[14:43:44.655761 ERROR] [openstudio.workflow.OSWorkflow] Found error in state 'EnergyPlus' with message: 'D:\OSN\src\workflow\RunEnergyPlus.cpp@291 : EnergyPlus Terminated with a Fatal Error. Check eplusout.err log.

Not sure if you've since updated the linked OSM, but I'm not getting the same warnings/errors. When I run your file with OpenStudioApplication v1.7.1 (SDK v3.7.0), I get a single error (in the non-empty run/eplusout.err file):

** Severe  ** createSpaceSurfaceLists: Space = SPACE 1093 has no surfaces.   
**  Fatal  ** GetSurfaceData: Errors discovered, program terminates.

SPACE 1093 is indeed a loner. Once deleted, simulations run yet with a bunch of warnings (all easily fixable IMO), and 3 similar (severe) errors (for SURFACE 1615, SURFACE 1702 & SURFACE 1447):

DetermineShadowingCombinations: ... is a casting surface and is non-convex.
Shadowing values may be inaccurate. Check .shd report file for more surface shading details

Hope this helps.

Got it, thank you! I appreciate your help on this. I'm not sure why I was having this issue, but since deleting space 1093 and fixing those surfaces, I am now able to run the simulation!
