New to recent builds, I have an R4 questionnaire that has valueExpression extensions in it...

org.hl7.fhir.exceptions.FHIRException: Unknown type Expression at org.hl7.fhir.convertors.VersionConvertor_30_50.convertType(VersionConvertor_30_50.java:3187) at org.hl7.fhir.convertors.VersionConvertor_30_50.convertExtension(VersionConvertor_30_50.java:417) at org.hl7.fhir.convertors.VersionConvertor_30_50.copyElement(VersionConvertor_30_50.java:102) at org.hl7.fhir.convertors.conv30_50.Questionnaire30_50.convertQuestionnaireItemComponent(Questionnaire30_50.java:128) at org.hl7.fhir.convertors.conv30_50.Questionnaire30_50.convertQuestionnaireItemComponent(Questionnaire30_50.java:161) at org.hl7.fhir.convertors.conv30_50.Questionnaire30_50.convertQuestionnaire(Questionnaire30_50.java:119) at org.hl7.fhir.convertors.VersionConvertor_30_50.convertResource(VersionConvertor_30_50.java:4850) at org.hl7.fhir.igtools.publisher.Publisher.generateRegistryUploadZip(Publisher.java:4728) at org.hl7.fhir.igtools.publisher.Publisher.generateZips(Publisher.java:4613) at org.hl7.fhir.igtools.publisher.Publisher.generate(Publisher.java:4364) at org.hl7.fhir.igtools.publisher.Publisher.createIg(Publisher.java:815) at org.hl7.fhir.igtools.publisher.Publisher.execute(Publisher.java:665) at org.hl7.fhir.igtools.publisher.Publisher.main(Publisher.java:6945)

Is this something that is known, or should I go look into the code to see if I can spot something?

do you get a stack dump?

Brian Postlethwaite (Feb 14 2020 at 03:55):

Sorry, yes

Whitespace was messing up the carriage returns

Brian Postlethwaite (Feb 14 2020 at 06:26):

From my looking at the stack, not sure why it would downgrade to the STU3 format, is that for the registry? Is there a way to turn that off (can't see it in the code) - if not can I add one?

Brian Postlethwaite (Feb 14 2020 at 06:36):

@Grahame Grieve, Yup, looking at the code referenced below, there is no mapping for the Expression type back to STU3, so what should occur in this case, should the resource just not be converted?
Have we had this case where a new extension type was introduced and a resource was being down converted for the registry?

Grahame Grieve (Feb 15 2020 at 02:32):

oh this is in code that is trying to produce R3 copies for the registry but this is not a thing anymore, so i'm going to get around to removing it

Brian Postlethwaite (Feb 15 2020 at 04:13):

Thanks. Is that to comment out the zip registry stage? (so I can do it locally)

Grahame Grieve (Feb 15 2020 at 04:39):

yes

Kevin Mayfield (Feb 15 2020 at 08:30):

Also happening on GraphDefinition and MessageDefinition. Stu3 (works on R4)

Grahame Grieve (Feb 17 2020 at 00:59):

please report stack dumps on this issue, so we can actually know what the problem is

Brian Postlethwaite (Feb 17 2020 at 01:33):

Both I assume, is that github issue or jira tracker?

Grahame Grieve (Feb 17 2020 at 01:38):

well.... we seem to be in disarray on that question. We have 2 camps well trained to use only one of those. and a third camp trained to just report issues here.\
