HL7 Validator PlanDefinition failed:

Question

I had to upgrade Hl7.Fhir.STU3 and Hl7.Fhir.Specification.STU3 library and now I am getting error message that it can't resolution PlanDefinition profile. I can see within the debugger that the specification.zip is being Extracted Extracted to 'C:\\Users\\dev\\AppData\\Local\\Temp\\FhirArtifactCache-1.2.1-Hl7.Fhir.STU3.Specification\\specification'}

Why will this not finding PlanDefinition?

{"Overall result: FAILURE (1 errors and 0 warnings)\r\n\r\n[ERROR] Resolution of profile at 'http://hl7.org/fhir/StructureDefinition/PlanDefinition' failed: Cannot prepare ZipSource: file 'D:\\Users\\mcdevitt\\Documents\\Visual Studio 2015\\FHIRValidatorFile\\FHIRValidatorFile\\FHIRValidatorFile\\bin\\Debug\\CustomProfiles' was not found (at PlanDefinition)"}

var HL7obj = new FhirXmlParser().Parse<PlanDefinition>(HL7FileData);
var coreSource = ZipSource.CreateValidationSource();
var cachedResolver = new CachedResolver(
            new DirectorySource(CustomProfilesPath, includeSubdirectories: true));

var combinedSource = new MultiResolver(cachedResolver, coreSource);

var ctx = new ValidationSettings()
        {
            ResourceResolver = combinedSource,
            GenerateSnapshot = true,
            Trace = false,
            EnableXsdValidation = true,
            ResolveExteralReferences = false
        };

var HL7validator = new Validator(ctx);
var result = HL7validator.Validate(HL7obj);

This error comes from the ZipSource not being able to find a zipped file at the listed path. Instead of the path to a folder, please indicate the zipfile that you want to use as source.

From the 'coreSource' name, I assume that you want to point to the base FHIR specification. Instead of supplying your own zipfile for that, you can change it to this line:

var coreSource = ZipSource.CreateValidationSource();

The library will locate the specification.zip that comes with it, and will then be able to use it for validation against the core spec.
