Hi Michael,

It's a little difficult to tell just from the description you provided what the problem exactly is, but my guesstimate would be that it actually is not related to the encoding (UTF8 vs ISO-8859-1) of what you are sending, but something to do with the response you are getting back.

As the error you quoted mentions - "... returned response with unexpected...".

And specifically the error is complaining about the content-type being text/html where it should probably be expected to be (in the case of SOAP) xml.

So it looks like you provided an extract from the SOAP log - but of what was sent (Output) but not what was received back.

Maybe share that part and we'd be able to help a little more.

You can use (inside %SYS) Config.Namespaces:Get().

For example -

%SYS > set status = ##class(Config.Namespaces).Get("USER",.properties)

%SYS > zwrite properties
properties("Globals")="USER"
properties("Library")="CACHELIB"
properties("Routines")="USER"
properties("SysGlobals")="CACHESYS"
properties("SysRoutines")="CACHESYS"
properties("TempGlobals")="CACHETEMP"
%SYS > set dataDatabaseName = properties("Globals")

%SYS > write dataDatabaseName
USER
%SYS > set codeDatabaseName = properties("Routines")

%SYS > write codeDatabaseName
USER

Of course assuming you are coming from other namespace into %SYS, you can have the name of that namespace in a variable, and use that variable instead of "USER" in my example above.

If you want the actual directory/folder of the database you can also then use Config.Databases:Get(), for example:

%SYS > set status = ##class(Config.Databases).Get("USER",.properties)

%SYS > zwrite properties
properties("ClusterMountMode")=0
properties("Directory")="C:\InterSystems\IRIS\mgr\user\"
properties("MountAtStartup")=0
properties("MountRequired")=0
properties("Server")=""
properties("StreamLocation")=""

And if you want directly just the locations of the databases, and not their names, you could use %SYS.Namespace:GetAllNSInfo() (without having to move into %SYS first) as @Julius Kavay mentioned.

For example:

USER > do ##class(%SYS.Namespace).GetAllNSInfo("USER",.info)

USER > zwrite info
info("GlobalDB","Directory")="c:\intersystems\IRIS\mgr\user\"
info("GlobalDB","Mounted")=1
info("GlobalDB","ReadOnly")=0
info("GlobalDB","Resource")="%DB_USER"
info("GlobalDB","Status")=1
info("GlobalDB","System")=""
info("RoutineDB","Directory")="c:\intersystems\IRIS\mgr\user\"
info("RoutineDB","Mounted")=1
info("RoutineDB","ReadOnly")=0
info("RoutineDB","Resource")="%DB_USER"
info("RoutineDB","Status")=1
info("RoutineDB","System")=""

In line with what @Yaron Munz was saying - when you purge your messages as part of your interoperability data, and you choose to include Message Bodies, then your Body class' data (whether your message body class extends from Ens.Request or Ens.Response, or whether it is simply a class extending from %Persistent) will get deleted together with the Message Header.

The purge code [in Ens.MessageHeader:Purge()] looks at the MessageBodyClassName and MessageBodyId fields of the MessageHeader record and then calls the %DeleteId() method for that class, for the given Id. 

That being said, as @Cristiano Silva pointed out if the class you use as your message body includes references to other persistent classes, these will not get deleted/purged with the referencing object, unless you have an %OnDelete callback method/Trigger taking care of this.

You can see these related posts I shared in the past -

Ran,

Thanks to @Tom Woodfin for finding this - there is a documented limitation for using || within properties that are part of an IDKEY, see from here:

   IMPORTANT:

   There must not be a sequential pair of vertical bars (||) within the values of any property used by an IDKEY index, unless that property is a valid reference to an instance of a persistent class. This restriction is imposed by the way in which the InterSystems SQL mechanism works. The use of || in IDKey properties can result in unpredictable behavior.

And also after some internal discussion - there is no way around this limitation.

This might be the simple case that when you paste with Ctrl-V into Terminal you get an unseen character (it's there you just don't see it)?

Worth trying... (try pasting with your mouse right-click or Shift+Insert) it could explain this "strange" behavior you are describing.

If this is the issue check out this article by @Eduard Lebedyuk 

If you are creating a FHIR Bundle manually (programmatically; as opposed for example of just getting a Bundle back as a search result response from our built-in FHIR Resource Repository) I think you should be using HS.FHIRServer.Util.Bundle:CreateBundle().

Indeed behind the scenes you can see it calls the CreateGUID() method @Marc Mundt pointed to populate the id -

Set bundle.id = $ZConvert($SYSTEM.Util.CreateGUID(),"L")

[The $ZConvert changes it to lower-case, e.g.:

USER>set guid = $SYSTEM.Util.CreateGUID()
 
USER>write guid
B990B74D-C008-4F4D-BA3B-4247A740250A
USER>write $ZConvert(guid,"L")
b990b74d-c008-4f4d-ba3b-4247a740250a

]

I actually saw now that the Wizard would work (as per above) also in Ensemble (I tested on v2018.1.x).

The fact that an SQL query just shows the OID, doesn't bother the Wizard to do it's job.

[If you take a peek at the code you can see it generates special stream handling -

; STREAMOUT()
 Do rtn.WriteLine("STREAMOUT(oref) {")
  ...
 do rtn.WriteLine(" while (oref.AtEnd = 0) {")
 do rtn.WriteLine(" set len = 32000")
 do rtn.WriteLine(" set val=oref.Read(.len)")
  ...
 do rtn.WriteLine(" write val")
 do rtn.WriteLine(" }")
  ...
