Validation Issue with LOINC Code Despite Successful $validate-code Check

[Jessie Liao]

Hi team,

I'm using hapi-fhir-jpaserver-starter(7.6.0) to build a FHIR server.

I have uploaded LOINC with hapi-fhir-7.6.0-cli tool by running upload-terminology command.

However when I run $validate operation on one of my examples ,get the response with HTTP Status Code ：422 and

Part of response like this：

            "diagnostics": "Unable to validate code http://loinc.org#8289-1 - Unknown code \"http://loinc.org#8289-1\". Code validation occurred using a ValueSet expansion that was pre-calculated at 2025-04-09T16:06:14.800+08:00 (5.9 days ago)",

            "location": [

                "Observation.code",

                "Line[26] Col[6]"

            ]

I checked with $validate-code operation

http://localhost:8080/fhir/CodeSystem/$validate-code?url=http://loinc.org&code=8289-1 .

And returns with  true

{

    "resourceType": "Parameters",

    "parameter": [

        {

            "name": "result",

            "valueBoolean": true

        },

        {

            "name": "display",

            "valueString": "Head Occipital-frontal circumference Percentile"

        }

    ]

}

I’m not sure why the $validate operation fails while $validate-code succeeds.
Is there something I might be missing — perhaps related to ValueSet expansion caching or configuration?

Any suggestions on what I could check would be greatly appreciated.

Thanks!

Jessie
