[HAPI] Investigate why _list doesnt seem to work

[MiskoG]

Prosper and Matthieu his dev are trying to integrate Cohort360 in Toulouse on our FHIR API.

They reached us because they want to use List ressource (I asked them why) but unfortunately the search /Patient?_list=... does not seem to work.

HAPI says it is supported since 5.3.3 version. HAPI in Toulouse and sandbox is 5.7.0.

I tried myself by creating a List with 3 patients

{
    "resourceType": "List",
    "id": "21302",
    "meta": {
        "versionId": "2",
        "lastUpdated": "2022-07-12T10:08:50.639+00:00",
        "source": "#opgqLcWHXBNpwpvN"
    },
    "status": "current",
    "mode": "snapshot",
    "entry": [
        {
            "item": {
                "reference": "Patient/d2eb38a2-032b-51db-ae1e-f855a5cdbd99",
                "type": "Patient"
            }
        },
        {
            "item": {
                "reference": "Patient/316a19ec-9c51-5f8e-b7c1-247938fc13ba",
                "type": "Patient"
            }
        },
        {
            "item": {
                "reference": "Patient/52e97967-0dc3-5d9a-b80e-1d789faf80e4",
                "type": "Patient"
            }
        }
    ]
}

But when I do https://sandbox.arkhn.com/hapi/fhir/Patient?_list=21302 I get all the server patients and not only the 3 included in the List.

Matthieu (the dev working with Prosper) did file an issue on hapi's repository https://github.com/hapifhir/hapi-fhir/issues/3761

@tevariou Do you have an idea, am I using the search or List creation properly ?

[tevariou]

I think so, it looks like a bug :/
