Frequent warnings: "Unhandled and unrecognized class/type: Reference"

[andrewcsmith]

Generally, whenever I'm deserializing something like a DiagnosticReport with a bunch of contained observations, I get the warning:

Unhanled and unrecognized class/type: Reference

However, the to_hash code clearly attempts to run FHIR.const_get('Reference'), which works perfectly well in my terminal. Is there any other reason this might happen?

Can you post a minimal sample DiagnosticReport and a few lines of code that reproduce the problem?
