Hi,

I am using snapshot version of hapi-fhir library and trying to validate observation with body height profile (http://hl7.org/fhir/StructureDefinition/bodyheight)
Also i use https://r4.ontoserver.csiro.au/fhir terminology service with RemoteTerminologyServiceValidationSupport
When the library tries to validate valueQuantity of observation, it fails with 400 http status code and message: If the code parameter is provided, the system parameter must also be provided.

Could you please check this issue, thx

@Roman Rodnin can you post an example resource you're trying to validate?

Michael Lawley (Apr 08 2020 at 00:18):

Note, the error mentioned means $validate-code is being called with a code parameter but no system parameter.
This is kinda strange given that the bodyheight profile has a mandatory fixed value for system

I'm going to assume @Roman Rodnin that you're using the new RemoteTerminologyServiceValidationSupport in 5.0.0-SNAPSHOT?

I have the same questions as the others, but I'm also just intertested to see this used in the wild already. :)

yes, you are right.
resource that i am trying to validate:

  }
}

I spent some time debugging this problem, but it's really hard to understand what's going on in InstanceValidator
I just found that in VersionSpecificWorkerContextWrapper line 450 there's codeSystem parameter is set to null
