Topic: Validator returns invalid OperationOutcome
Reece Adamson (Jun 18 2020 at 21:02):
We discovered this while working directly with the ValidationEngine class in Java, but it is reproducible with the Desktop JAR validator.
The HL7 Validator returns an invalid OperationOutcome. The main issue we noticed is that it does not include an OperationOutcome.issue which has a cardinality of 1..1 in the base FHIR spec. I'm not sure if this is related to the lack of suitable codes for OperationOutcomes when reporting successful outcomes which was discussed at DevDays and spawned FHIR-27840.
For example trying to validate a simple patient ( e.g. patient.json )
FHIR Validation tool Version 5.0.7-SNAPSHOT (Git# 6bc790d98b04). Built 2020-06-07T08:35:37.25+10:00 (11 days old)
Detected Java version: 11.0.7 from /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home on x86_64 (64bit). 4096MB available
Arguments: patient.json -output out.json
Directories: Current = /Users/crowleyj/Downloads, Package Cache = /Users/crowleyj/.fhir/packages
.. FHIR Version current, definitions from hl7.fhir.r5.core#current
.. connect to tx server @ http://tx.fhir.org
(vcurrent)
.. validate [patient.json]
This provides this operation outcome (out.json)
{
"resourceType" : "OperationOutcome",
"text" : {
"status" : "extensions",
"div" : "<div xmlns=\"http://www.w3.org/1999/xhtml\"><p>All OK</p></div>"
},
"extension" : [{
"url" : "http://hl7.org/fhir/StructureDefinition/operationoutcome-file",
"valueString" : "patient.json"
}]
Subsequently trying to validate the provided OperationOutcome gives:
$ java -jar org.hl7.fhir.validator.jar out.json
FHIR Validation tool Version 5.0.7-SNAPSHOT (Git# 6bc790d98b04). Built 2020-06-07T08:35:37.25+10:00 (11 days old)

Let me know if we can help provide further information and, as always, thanks for the hard work on these tools!

oops. I really though I had fixed that. But I missed it somehow. Fixed next release
