Need better detailed error message for $evaluate-measure operation failure.

[PreetiG9]

Test Steps:

Scenario 1:

• Uploaded a measure

CMS986FHIR-v1.0.000-FHIR.json

• Performed evaluate operation.
  Result:
  15:00:40.893 [fhir_endpoint.fhirEndpointServer-181] WARN M:fhir_endpoint R:1584dSWQggavrv9L T: S: J: C: c.u.f.r.s.i.ExceptionHandlingInterceptor - Failure during REST processing: ca.uhn.fhir.rest.server.exceptions.InvalidRequestException: Aggregation method: Sum is not a valid value for Measure: https://madie.cms.gov/Measure/CMS986FHIRMalnutritionScore

{ "resourceType": "OperationOutcome", "issue": [ { "severity": "error", "code": "processing", "diagnostics": "HAPI-1744: Failed to parse match URL[Measure?url=https://madie.cms.gov/Measure/CMSFHIR844HybridHospitalWideMortality&version=Draft based on 0.5.001] - URL is invalid (must not contain spaces)" } ] }%

Expected : Error message was misleading as it literally expects "sum".

Scenario 2:

• Uploaded a measure with value stratifier + valid CQL expression expression(response List).

ResourceMeasureTest.json

• Performed $evalaute-measures.
  "stratifier": [ { "id": "stratifier-1", "code": { "text": "all encounters" }, "component": [ { "id": "stratifier-1-comp-1", "code": { "text": "all encounters" }, "criteria": { "language": "text/cql.identifier", "expression": "All Encounters" } } ] } ]
  Result: MeasureReport generated with error status.- Expected.
  But Message is not related to actual failure reason.

@barhodes suggestion is the best course of action for a fix here:

I would suggest an error message akin to "Unrecognized code for aggregate method, expected a code from the preferred ValueSet Measure Aggregate Method, possible values ..."
