Hi All,

The  problem is in HS.FHIRServer.RestHandler

Class HS.FHIRServer.HC.FHIRInteropAdapter Extends HS.FHIRServer.RestHandler
{ Parameter isInteropAdapter As %Boolean = 1; Parameter ServiceConfigName As %String = "InteropService"; }

For some reason its not allowed to send the bearer token with the unauthenticated application:

// Access token present on unsecure CSP request is invalid. Otherwise, if access
// token found on secure CSP request then add to FHIR request AdditionalInfo for
// later evaluation by the FHIR service.
If '%request.Secure {
If ($ZConvert($Piece(%request.GetCgiEnv("HTTP_AUTHORIZATION")," ",1),"U") = "BEARER") || ($Get(%request.Data("access_token",1)) '= "") {
Set %response.Status = ..#HTTP401UNAUTHORIZED
Return $$$OK
Set accessToken = ""
Else {
// InterSystems FHIRServer policy is to NOT allow passing access token in the
// request URL or form encoded body (either can be found in %request.Data).
If $Get(%request.Data("access_token",1)) '= "" {
Set %response.Status = ..#HTTP401UNAUTHORIZED
Return $$$OK
Set accessToken = ##class(%SYS.OAuth2.AccessToken).GetAccessTokenFromRequest(.tSC)
If accessToken '= "" {
Do tRequest.AdditionalInfo.SetAt(accessToken, "USER:OAuthToken")
Do tRequest.AdditionalInfo.SetAt(hsrestconfig.OAuthClientName, "USER:OAuthClient")

We're gonna discuss the issue with intersystems but it looks like we need custom programming to make this situation work in the new HC version.

Thank you @Alister Pino and @Julius Kavay for your help.

In this scenario see the final solution below:

ClassMethod MergeDynamicObjects(ObjComplete As %Library.DynamicObject, ObjAddendum As %Library.DynamicObject) [ Final ]
  Set obj1 = ObjComplete.%Get("OptOuts")
  Set obj2 = ObjAddendum.%Get("OptOuts")     
  Set OptOuts2Iter = obj2.%GetIterator()
  While OptOuts2Iter.%GetNext(.key , .value ) {
    Do obj1.%Push(value)
  return ObjComplete

Hi @Stefan Wittmann,

I was just curious about this functionality. For a project I need to convert ORU~R01 to MDM~T02 messages. 

For now it's fine to write the DTL by myself (small messages). I would be happy to see this functionality in a further release. It can indeed be very useful with migration projects.

Hi all,

I was wondering in which version I can find the DTL Generator, or is it still in development?

In version ' IRIS for Windows (x86-64) 2020.1.1 (Build 408U) Sun Mar 21 2021 22:04:53 EDT' I cannot find it.

Hello Sean,

Great, this helps me a lot. I've got a working situation right now. I think the mistake that I made is that I add .cls after the name of the service.
