I have to implement a custom query result to be returned using the FHIR Bundle Resource.

I am a novice and not well versed in InterSystems yet so please excuse mistakes due to ignorance.

I am trying to do package mapping in the %ALL NameSpace.

I create a new Package Mapping entry and select my database bu the "Package Name" combo box never populates the packages in this database so I cannot select it, see screenshot below, the "Package Name" list remains empty. There definately are packages in that database. Why is this happening? Did I miss a setting?

I am trying to create REST API following these instructions:  https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls?KEY=GREST_apimgmnt

However it does not work.

I tried downloaded the v2.0 schema.json of the OpenAPI specification and pasted it on Postman with the parameters as speicifed, but I get this error message back:

{
    "msg": "ERROR #8738: Correct OpenAPI 2.0 version was not specified: . <$.swagger>\r\n  > ERROR #5490: Error running generator for method '%OnCompile:TasksRestApp.spec' \r\nERROR: %REST.Spec.cls(%OnCompile) of generated code compiling subclass 'TasksRestApp.

When reading %GlobalBinaryStream into a %String I am aware therte is a size limit of 3,6MB.

My question is since %Binary is underlying a %String is there a limit on this as well?

Can I safely read any size %GlobalBinaryStream into a %Binary?

When using $SYSTEM.Status.DecomposeStatus(tSC, .tErrorList) in ObjectScript to get the lsit of errors (I need to do this so that I can generate a custom JSON with the error messages) what is the type of tErrorList returned and how to intialize?

I need to know the type to iterate through it, I have tried dynamic array methods sich as %Size() also $LISTLENGTH to get the size, but both fails, so obviously not that, and being new to InterSystems I find the documentation assumes a new person knows what is behind the classes and how it was implemented from the start.

I have SQLCompute with SQLComputeCode on a couple of Properties in my class.

These work fin when I insert/update via ObjectScript or SQL from the ManagementPortal.

However, if I insert (create new record) via my C# app using the Caché ODBC DLL the SQLCompute is ignored, it does not run.

Is this expected InterSystems Caché behaviour? We are on latest IRIS platform.

I am sending a PUT FHIR message for a CodeSystem Resource using the defailt Service and server that was installed when I installed the FHIR on the NameSpace.

When I try to use the FHIR Request "id" property it is empty; e.g. pFHIRRequest.id is EMPTY. I really need to get this value, how can I get it?

I added a trace ion both the HS.FHIR.Service and HS.FHIR.Server.Process, details to follow:

The trace in HS.FHIR.Service is as follows, this is inside the OnProcessInput where the Id is validated I added the "else", it prints the line in the "else" and the result is an EMPTY input.

I am de-serialzing a FHIR Resource CodeSystem in STU3 FHIR resources from JSON in my Business Process using the following code:

set pCodeSystemResource = ##class(HS.FHIR.vSTU3.Model.Resource.CodeSystem).%New()
set tStream = ##class(HS.SDA3.QuickStream).%OpenId(pFHIRRequest.QuickStreamId)
if $IsObject(tStream) {
    set tSC = ##class(HS.FHIR.Utils).FHIRToHSFHIR(pFHIRRequest.ContentType, tStream, .pCodeSystemResource, "HS.FHIR.vSTU3.Model.
