Vonk FHIR server Bundle validation issue - hl7-fhir

Question

When posting the FHIR example that uses the ZIB for tobacco use to the Vonk FHIR server in a transaction, Vonk responds with an error.

It seems the error complains about an URL mismatch in the PackYears component, however, that is exactly using the url http://unitsofmeasure.org as indicated should be used in the error. Does anybody know if the request is wrong here or Vonk has an issue?
Notice that posting without a transaction to /Observation/ does NOT give an error but completes successfully.
Also notice that the /Bundle/$validate request for the same bundle does NOT indicate any errors, but responds with The operation was successful.
We are using Vonk 1.1.0 and have configured it to use a SQL Server database.

Answer 1

The error is in Vonk. I can reproduce it with Vonk version 1.1.0. We will release a new version of Vonk next week, where this has been resolved.
