In Cypress 4.0.2, I'm running into an issue with c1 sample testing for the "Substance, Administered" template. When testing the attached file with "Substance Administered" as a selected data criterion, we get a "C1 Execution: An internal error occurred" message. When I swap out the Substance, Administered" data criterion, the file passes.

I've included the Production error message which pointed me to /lib/validators/attribute_extractor.rb where it seems to be failing to extract the 'relevantPeriod' => 'cda:effectiveTime/cda:low from the template.
