I am quite new in FHIR development. f I try to do the same thing with the other public test server (https://server.fire.ly) This is my code getting below exception. Hl7.Fhir.ElementModel.StructuralTypeException: Type checking the data: Encountered unknown element 'timestamp' at location 'Bundle.timestamp[0]' while parsing\r\nAre you connected to a FHIR server with FHIR version 3.0.2? Try the FhirClientSetting.VerifyFhirVersion to ensure that you are connected to a FHIR server with the correct FHIR version.\r\n
