I’m using hapi-fhir version 7.2.1 and I’m trying to convert a CDA document in FHIR resource by using FHIR Mapping language and StructureMap resources

I wrote this unit test

@SpringBootTest(
    webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
    classes = {FhirCda2FhirServerApplication.class})
@ExtendWith(SpringExtension.class)
@Slf4j
public class CdaToFhirTests {
  @Autowired
  @Qualifier("fhirJsonParser")
  private IParser jsonParser;

  @Autowired private FhirContext fhirContext;
  @Autowired private DefaultProfileValidationSupport defaultProfileValidationSupport;
  private static IWorkerContext workerContext;


  @Test
  public void testCdaToFhirConverter() throws Exception {
    log.info("Test CDA to FHIR converter");

    // prePopulatedValidationSupport.addStructureDefinition(sd);
    HapiWorkerContext hapiWorkerContext =
        new HapiWorkerContext(fhirContext, defaultProfileValidationSupport);
    hapiWorkerContext.allStructures().stream()
        .forEach(
            structureDefinition -> {
              log.info(
                  "StructureDefinition type {} url {}",
                  structureDefinition.getType(),
                  structureDefinition.getUrl());
            });

    log.info("ALL STRUCT {}", hapiWorkerContext.allStructures());
    FileSystemResource cdaXmlResource = new FileSystemResource("ccda.xml");
    StructureMap structureMap =
        jsonParser.parseResource(
            StructureMap.class, new FileSystemResource("StructureMap.json").getInputStream());
    log.info("Loaded StructureMap {}", structureMap);
    StructureMapUtilities utils = new StructureMapUtilities(hapiWorkerContext);
    Element parsedCda =
        Manager.parse(hapiWorkerContext, cdaXmlResource.getInputStream(), FhirFormat.XML);
    Bundle target = new Bundle();
    utils.transform(null, parsedCda, structureMap, target);
    log.info("Bundle {}", jsonParser.encodeResourceToString(target));
  }
}

But when I execute it I get this error:

org.hl7.fhir.exceptions.FHIRFormatError: This does not appear to be a
FHIR resource (unknown namespace/name
‘urn:hl7-org:v3::ClinicalDocument’) at line 0 col 0

I can’t figure out what I’m missing. May anybody give me a tip?
