Topic: Validation error on simple example

Kirt Noel (Oct 15 2019 at 19:22):

I am having difficulty validating a resource with the C# API against profile I created with Forge.

Here's the error I'm encountering:

[ERROR] Unable to resolve reference to profile 'http://hl7.org/fhir/StructureDefinition/Patient' (at Patient)

Any guidance would be appreciated.

Here's the relevant excerpt from my code:

var myProfiles = new CachedResolver(new MultiResolver(
new DirectorySource(@"\\mySharedDrive\StructureDefinitions")));

var patientProfile = myProfiles.FindStructureDefinition(@"http://example.org/fhir/StructureDefinition/CustomPatientProfile");

Patient patientResource = ...

var validator = new Validator();
var outcome = validator.Validate(patientResource, patientProfile);

It can possibly mean that the directory where the zip gets extracted to is corrupted - find and delete it

I don't have the name of the folder offhand, but I've seen this error before, and that was the fix.

I simply saved the profile into a directory without zipping it. As such, I didn't invoke: ZipSource.CreateValidationSource()
In iterating with the debugger it seems the profile was loaded from the directory and it subsequently populated the patientProfile variable cited above.

Hi Kirt,

It cannot find the basic Fhir resource Patient. In your resolver structure I miss the zip file with all the standard Fhir resources. When you use the following resolver structure , the validator should be able to find the standard Patient resource:

var myProfiles = new CachedResolver(new MultiResolver(new DirectorySource(@"\\mySharedDrive\StructureDefinitions"), ZipSource.CreateValidationSource()));

Hello Marco.

You correctly identified the problem. Indeed, the folder did not have a copy of the specification.zip in it. Upon placing it there, the error was corrected and the validator was able to resolve both the specification and my Patient profile.

Thank-you!
