Possible causes for "Optional is not initialized" error in an OpenStudio Results measure?
Hi there, I am getting the following error when attempting to run a measure to specify single DX heating and cooling
Found error in state 'os_measures' with message :/ruby/2.7.0/gems/openstudio-workflow-2.3.1/lib/openstudio/workflow/util/measure.rb failed with message Runner error :/ruby/2.7.0/gems/openstudio-workflow-2.3.1/lib/openstudio/workflow/util/measure.rb failed with Optional not initialized, C:/Users/AppData/Local/Temp/osmodel-1684756282-1/resources/measures/a_20230522_ashptest_1 1 1 1 1/measure.rb:34:in `get'
Not sure where to start with debugging this, and the only other post I can find online related to this error does not seem relevant to my own context. Any help would be appreciated in figuring out when this type of error arises, and what possible next steps are to resolve - thank you!
This is a new measure you're developing? Or the NREL OpenStudio Results Measure? Could you post the 3 or 4 lines preceding line 34 (e.g. lines 30 to 34) in
measure.rb? Sounds like a (common) Boost optional issue.Agreed. Read the section "OpenStudio Measures and the boost::optional Type" from the measure writing guide.
I see - thank you, both! That documentation is helpful.
