I am using eppy to run a series of premade IDF files. I have used the code segment described in "Running in parallel processes using Generators." in the eppy documentation. The code segment works perfectly for smaller series of IDF files, but I start getting errors, then I add up to 10000 plus IDF files in the queue. My error right now:

Program Version,EnergyPlus, Version 8.9.0-40101eaafd, YMD=2022.07.11 15:00,
** Severe  ** <root> - Missing required property 'GlobalGeometryRules'.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

But the GlobalGeometryRules are in the IDF files for the given file. Therefore I am inclined to believe the error is occurring. Then I run many IDF files (10000+). Therefore I would be interested if anyone knew how to catch these errors in the Eppy foundation before it crashes my program.

def make_eplaunch_options(idf):
"""Make options for run, so that it runs like EPLaunch on Windows"""
idfversion = idf.idfobjects['version'][0].Version_Identifier.split('.')
idfversion.extend([0] * (3 - len(idfversion)))
idfversionstr = '-'.join([str(item) for item in idfversion])
fname = idf.idfname
options = {
    'ep_version':idfversionstr, # runIDFs needs the version number
return options

def energy_simulations(recipe, log, config, fnames):
Run all no-MSF energy simulations

iddfile = os.path.join(config.getValue('path', "energyplus"),"Energy+.idd") 
log.debug("Energyplus ...

Sorry I am seeing this question rather late can you open this issue in github https://github.com/santoshphilip/eppy...

This may take a bit of back and forth to tease out the problem (and maybe update eppy)
