Try adding a $$$TRACE in this method:

Method OnAssociationReleased(pSourceConfigName As %String, pInput As EnsLib.DICOM.Notify.Released) As %Status
{
    #dim tSC As %Status = $$$OK
        
        #; The association between this process and the operation has been released, so we are now
        #; not connected to the operation
        Set ..CurrentState="OperationNotConnected"
    
    ; Añadimos 11 10 2023
    
    
    Set tSC=..SendRequestAsync("EnrutadorConsultarEstudiosVNAv01r00",..respuestaConsultaEstudios,0)
    
    Quit tSC
}

Maybe you are calling the BP from here with a null response.

Here you can see an example:

ClassMethod ImportRawMatches() As %DynamicObject
{
    Try {
        Do ##class(%REST.Impl).%SetContentType("application/json")
        If '##class(%REST.Impl).%CheckAccepts("application/json") Do ##class(%REST.Impl).%ReportRESTError(..#HTTP406NOTACCEPTABLE,$$$ERROR($$$RESTBadAccepts)) Quit
        
        set newRequest = ##class(QUINIELA.Message.OperationRequest).%New()
        set newRequest.Operation = "Import"
        
        set status = ##class(Ens.Director).CreateBusinessService("QUINIELA.BS.FromWSBS", .instance)
       	set response = ##class(QUINIELA.Message.ImportResponse).%New()
        set response.Status = "In Process"
        set response.Operation = "Import"
        set status = instance.SendRequestAsync("QUINIELA.BP.ImportBPL", newRequest, .response)
        
        if $ISOBJECT(response) {	        
            Do ##class(%REST.Impl).%SetStatusCode("200")
            return response.%JSONExport()
		}		
        
    } Catch (ex) {
        Do ##class(%REST.Impl).%SetStatusCode("400")
        return ex.DisplayString()
    }

The key is this row:

return response.%JSONExport()

Well, in theory if you define the identifier in the request section and define the method as "PUT" the server should create the organization if it doesn't exist or updated if it do.

But this is the theory...not sure if it will work for your FHIR server.
