Hello,
I have a problem with a FHIR Interop scenario that the HTTP Header Value content-type between IRIS and client changes in case of an error (HTTP 422). If I set the status in the response to 200 OK as the last step in the service class, the return transmission works.
Within my operation class, the error code is taken from the source system and entered in the HS.FHIRServer.Interop.Response message.
