How to debug OpenStudio measure

I am trying to run OpenStduio measure to create FCU with DOAS system
However, I get error as below.
Since I am new to work with OpenStudio measure, I wonder how I can approach to this problem.
Can anyone tell me appropriate approach to this issue?

Standard Output:

Line 122 of the OsLib_HVAC.rb file is:

spaceType = space.spaceType.get

Calling the spaceType method on a Space object returns an OptionalSpaceType object. If you try to get and Optional type that doesn't point to an acutal object, you will recieve the 'Optional not initialized' error. See the Measure Writing Guide section on the boost:optional type.

Based on this I would surmise you are trying to run the measure on a model that has spaces without space types assigned.

The right way to handle this case in the measure would be to check if space.spaceType.is_initializedor if not space.spaceType.empty? and then call space.spaceType.get if true, and (perhaps) skip that space if false.

According to your comment, I tried to investigate the script and I suspect below sentence is causing problem.

zonesSorted = OsLib_HVAC.sortZones(model, runner, options, space_type_to_edits_hash)

However, since I am new to ruby and OS api, I cannot imagine what this script actually does. Referring to my experience from Python, I would print the variable for debugging in this case. Are there similar function I can use in this case?

The problem is caused by space.spaceType.get trying to get an empty space type. The first line after the error message in the standard output tells you which line in what file is causing the error. In ruby, you can use puts to print variables/objects/whatever to help debug. Or all these other ways.
