Hi all - I'm evaluating if HAPI FHIR can support Quality Measures using QICore 6. I have the following Implementation Guides Loaded (mostly - the packages appear to need a little massaging because some of the resources reference invalid resources such as DeviceUsage):

- hl7.ter...@5.4.0

- hl7.termi...@5.0.0

- hl7.fhir.uv...@1.0.0

- hl7.fhir...@6.1.0

- hl7.fhir....@6.0.0

I'm using ELM's and Sample FHIR bundles released on MADiE (I know they work).

However, every time I evaluate a measure on HAPI (example - http://127.0.0.1:8080/fhir/Library/31754/$evaluate), the numerator, denominator, and every other parameter for that matter comes back with something like:

{

            "name": "Denominator",

            "_valueBoolean": {

                "extension": [

{

                        "url": "http://hl7.org/fhir/StructureDefinition/cqf-isEmptyList",

                        "valueBoolean": true

}

]

}

},

{

            "name": "Denominator Exclusions",

            "_valueBoolean": {

                "extension": [

{

                        "url": "http://hl7.org/fhir/StructureDefinition/cqf-isEmptyList",

                        "valueBoolean": true

}

]

}

},

I'm fairly confident that my measurementperiod params are set correctly. I'm becoming worried I'm going down a rabbit hole and will eventually find that HAPI, for whatever reason, won't work with QI-Core 6.

I'm wondering if anyone has any experience setting this up and any online documentation that can provide a high-level check list of requirements and dependencies. I'm feel I'm either really close to having it working, or there is some missing component that prevents QICore 6 from working at all on HAPI.
