Topic: Support for $lookup operations
Santosh Jami (Aug 15 2020 at 11:07):
I am trying the following $lookup operation on hapi FHIR server and get the desired result,
API Call:
http://hapi.fhir.org/baseDstu3/CodeSystem/$lookup?system=http://loinc.org&code=5792-7&_format=json
Result:
"Glucose [Mass/volume] in Urine by Test strip"
But when I try the same on Vonk, I get a 404- Am I missing something?
https://vonk.fire.ly/administration/CodeSystem/$lookup?system=http://loinc.org&code=5792-7&_format=json'
"issue": [
{
"severity": "error",
"code": "code-invalid",
"details": {
"coding": [
{
"system": "http://hl7.org/fhir/dotnet-api-operation-outcome",
"code": "6005"
}
],
"text": "CodeSystem does not exist for provided system/code combination."
}
}
And with this URL
http://tx.fhir.org/R4/CodeSystem/$lookup?system=http://loinc.org&code=5792-7&_format=json
I get 404, "Document /R4/CodeSystem/$lookup not found"
Is the $lookup operation not implemented on Vonk and Health Intersections reference server?
Am I missing something in the GET operations that I am invoking?

Use /r4 not /R4 for tx.fhir.org also works with https://r4.ontoserver.csiro.au/fhir/CodeSystem/$lookup?system=http://loinc.org&code=5792-7&_format=json

Thanks @Michael Lawley - using /r4 works.
Just need to ensure, I can get this working for Vonk - hope it just a URLfix and not a "not supported feature".
