I have an OpenStudio file with weather file .epw and just want to run the simulation without any sizing based on design days. I removed the design days selected

but got error

see attached OSM file ...ok can not be attached :(

I can see that my eplusout.err is empty
Q1. Is it possible to run simulation without design days?
Q2. why can not see an error?
