Specific FHIR Observations requested are not being returned #1154

Closed euanmillar closed 2 years ago

Hi,

I wonder if you can help me. I am experiencing a strange issue on some code that previously worked fine for me. My code requests a specific Observation from Hearth via OpenHIM. I know that the Observation does not exist so I expect to receive a not found or null response. However rather than return the specific Observation requested, OpenHIM responds with the only Observation available.

I am currently running OpenHIM v5.

I have saved an Encounter with a single custom Observation. 

{"resourceType":"Bundle","id":"e18c4418-8b4f-4436-a309-63b08c42efc2","meta":{"lastUpdated":"2021-10-22T13:25:52.344+00:00"},"type":"searchset","total":1,"link":[{"relation":"self","url":"http://localhost:3447/fhir/Observation"}],"entry":[{"fullUrl":"http://localhost:3447/fhir/Observation/39d16603-d063-427b-98c1-9c06fe9ff4ad/_history/c08831aa-a3a6-4f19-904f-89904bdd40ff","resource":{"resourceType":"Observation","status":"final","context":{"reference":"Encounter/493bd7d7-1879-4e81-a675-0fe316c7641c"},"category":[{"coding":[{"system":"http://hl7.org/fhir/observation-category","code":"procedure","display":"Procedure"}]}],"code":{"coding":[{"system":"http://loinc.org","code":"present-at-birth-reg","display":"Present at birth registration"}]},"valueString":"MOTHER","meta":{"lastUpdated":"2021-10-22T13:25:38.155+00:00","versionId":"c08831aa-a3a6-4f19-904f-89904bdd40ff"},"id":"39d16603-d063-427b-98c1-9c06fe9ff4ad"},"request":{"method":"POST","url":"Observation"}}]}

But of course it is possible for an Encounter to have many Observations. I have code that requests each one individually so that I can do specific things with each Observation.

If I request an Observation that I know does not exist, like this to retrieve body weight:

/Observation?encounter=Encounter/493bd7d7-1879-4e81-a675-0fe316c7641c&code=3141-9

Then I would expect to receive either the body weight observation or nothing at all. However I receive the custom observation instead. The only Observation available in the Encounter.

Is there any config step that I have missed to ensure that this URL only returns body weight or nothing?

Many thanks to you.

Sorry this was my fault in the end. No issue, OpenHIM is working great thanks.
