getFile from rest api and swagger

Question 1

Sylvie Greverend · 2 jul, 2024

I use a swagger file and ##class(%REST.API).CreateApplication to create the rest api.

There is an interesting post: https://community.intersystems.com/post/download-file-rest-api-operation, but it is code, not a swagger configuration. disp.cls returns always a header content : application/json that of course fails as I am not always returning a json

I can not figure out what to put in swagger. Some examples I tried:

produces:
- application/pdf
- image/png

responses:
200:
schema:
type: file
responses:
200:
schema:
type: string
format: binary

Thank you

Question 2

#Compilador #ObjectScript #InterSystems IRIS

I have a class with two methods

Class Foo.Bar
{

ClassMethod Helper()
{
// do something
}

ClassMethod Generated() [ CodeMode = objectgenerator ]
{
do ..Helper()
// do something else
}

}

Since the method Generated is run before the class is compiled, the call to do ..Helper() fails. Is there a way around this other than manual inlining?

Hello Community,

I'm a beginner and currently working on a project to convert CCDA files to FHIR using InterSystems IRIS. I have developed a web form to upload CCDA files, and I'm attempting to convert the uploaded CCDA files to FHIR. However, I am encountering an issue where the conversion process results in an empty entry.
Here's the Output it displays on HTML page:

Size of CCDA Stream: 74152
vR4
{"resourceType":"Bundle","type":"transaction","entry":[]}

Here is my code: CCDtoFHIR.csp

Problem Description:

The CCDA file uploads successfully, and I can see the size of the uploaded stream.
The transformation to SDA3 seems to work fine without errors.
The conversion from SDA3 to FHIR appears to be successful, but the resulting FHIR bundle is empty.

Debugging Steps:

I've ensured that the CCDA stream is read correctly.
I confirmed that the transformation to SDA3 does not produce any errors.
I attempted to output some content from the SDA3 stream, which seems fine.
The FHIR transformation does not produce any errors, but the resulting FHIR bundle is empty.

Questions:

What could be the reason for obtaining an empty FHIR bundle after the transformation?
Are there any additional debugging steps or checks I can perform to identify the issue?
Is there a specific configuration or additional steps required for the HS.FHIR.DTL.Util.API.Transform.SDA3ToFHIR transformation process?
