CLI Validator | Resolving of external profile urls not working

[sebastianhelbig]

The resolving of external (not supplied by an IG) profiles is not working for me.

Simple example: I download the following ressource example: https://simplifier.net/bfarm/example-diga-healthapp

java -jar validator_cli.jar Example-DiGA-HealthApp.xml -version 4.0.1 -debug -locale en-US -language en

I can see on the webserver that https://fhir.bfarm.de/StructureDefinition/HealthApp is fetched by the validator. I tested with returning the profile as fhir+json and fhir+xml. Right now it will serve based on the given accept header and redirect to simplifier for text/html with supplying fhir+xml as the default.

I don't believe that there's any documentation to say that it should work like this. I don't believe that this is true either:

I can see on the webserver that https://fhir.bfarm.de/StructureDefinition/HealthApp is fetched by the validator.

it it's true, I can't see why. The intent is that you nominate the profiles to fetch using the -ig parameter e.g. -ig https://fhir.bfarm.de/StructureDefinition/HealthAppMedia. There's a bug that means that won't work, but will start working from the next release

Nevermind. It is working, I just didn't notice that the error message had changed. The profile urls should point to snapshots of the profiles and validation works fine. (of course without the need to supply the -ig param).
