unhelpful error when referenced file not found or empty

[ctaggart]

I'm working on Azure/azure-rest-api-specs#6653 by adding examples. I've started adding the x-ms-examples. I create the blank examples and ran this tool. It was not helpful:

root@7fe462c08598:/src# oav validate-spec vmwarevirtustream.json
{ level: '\u001b[31merror\u001b[39m' }
{ message:
   'RESOLVE_SPEC_ERROR: internal error: Cannot read property \'Symbol(@ts-common/source-map/object-info)\' of null.',
  level: '\u001b[31merror\u001b[39m' }
{ message: undefined, level: '\u001b[31merror\u001b[39m' }
{ message:
   'fatal error: internal error: Cannot read property \'Symbol(@ts-common/source-map/object-info)\' of null, {"code":"INTERNAL_ERROR","id":"OAV100","message":"internal error: Cannot read property \'Symbol(@ts-common/source-map/object-info)\' of null","innerErrors":[{"message":"internal error: Cannot read property \'Symbol(@ts-common/source-map/object-info)\' of null","code":"INTERNAL_ERROR","id":"OAV100","innerErrors":[{"level":"error"}]}]}',
  level: '\u001b[31merror\u001b[39m' }

I was expecting to give more useful error information like :

@ctaggart, what blank example do you mean? Does it like below?

{
  "parameters": {
    "subscriptionId": "{subscription-id}",
    "api-version": "2016-09-01-preview"
  },
  "responses": {}
}

@ctaggart, I cannot repro this issue with blank example. The error above you mentions is for sematic validation instead of model validation. I close this issue for now and please feel free to re-open it if you still see this issue.
