For later reference the issue was duplicated naming of the zone that made EP simulation to crash. The warning for “no .eio file found.” is usually the result of a failed energy simulation so you need to go back and check why EnergyPlus failed to run the analysis.
This is my fault for writing a bad warning on the Read EP Result component. I just put in a better one that includes instructions for what you should do when the Read EP component fails. Check the report out the Run Simulation component to find what is going wrong with your simulation.
