FHIR Bridge - Diagnostic Report & MedicationStatement


I have been testing in the last time working of FHIR Bridge using a attached Postman collection and I’ve encountered some issues with 2 requests - Post DiagnosticReport and MedicationStatement. When trying to send DiagnosticReport there is:

An error has occurred: Coding must have a display or TerminologyService must not be null

With MedicationStatement:

{"error":"Unprocessable Entity","message":"/content[openEHR-EHR-OBSERVATION.medication_statement.v0, 1]/data: Attribute data of class OBSERVATION does not match existence 1..1"}

The requests are as they were in the collection and I did not changed anything. Did anything changes in working of FHIR Bridge for those objects?

Thank you

  1. You need a terminologyService for that example as explained.

  2. maybe that request is just old and the validation of ehrbase is more rigid now compared to back then.

Thanks Severin. I resolved the first issue with terminologyService, however still no idea with second one. Isn’t the validation of request connected with the OPT template that FHIR Bridge contains?

The second error is saying that the mandatory data tree in the medication statement is not being populated. Can you post a sample of the original fhir bundle?

Sure, this is the fhir bundle that I am trying to send:

    "resourceType": "MedicationStatement",
    "meta": {
        "profile": [
    "status": "active",
    "medicationCodeableConcept": {
        "coding": [
                "system": "http://snomed.info/sct",
                "code": "413591007",
                "display": "Product containing atazanavir (medicinal product)"
                "system": "http://fhir.de/CodeSystem/dimdi/atc",
                "code": "J05AE08",
                "display": "Atazanavir"
        "text": "Atazanavir"
    "subject": {
        "reference": "/Patient?identifier=urn:ietf:rfc:4122|{{patientId}}",
        "identifier": {
            "system": "urn:ietf:rfc:4122",
            "value": "{{patientId}}"
    "effectiveDateTime": "2020-10-19T08:43:33+02:00"

Thanks - nothing unusual to see there. Can you share the target .opt? THere was no collection attached that I can see.

This is the opt file (this he above bundle is sample request from FHIR Bridge):
