I found that issue here
https://github.com/NREL/openstudio-calibration-gem/issues/11

But it has been fixed in the current version of the measure. It has get.solarAbsorptance instead of get.getSolarAbsorptance.

I'll investigate why you are getting an updated version on BCL. Looks like it was last updated on BCL in Nov 2021 and the measure was fixed Feb 2021
