NullPointerException if YAML contains external ref

[thisiskarthikj]

Swagger2Markup version: swagger2markup-cli-1.3.3.jar

Problem description:

I have the following YAML which has a path referencing an external (working) YAML and the corresponding object is specified with YAML anchors. When I verify the swagger document in the UI, I do see the api definition (retrieved from the external server) but when I run the following command to generate the adoc, I get NullPointerException

info:
  title: abc REST API specification
  description: >-
    test
  version: 4.0
schemes:
  - http
paths:
  /catalog/v1/config:
      $ref: "http://abc:31820/static/abc-rest-api.yaml#/paths/~1config"

I tried adding the swagger2markup.interDocumentCrossReferencesEnabled=true property to the config file and still ended up with NPE. Any help appreciated !

Sry I'm too busy at the moment with Resilience4j.
Did you try to debug it?

I guess it's a problem of the SwaggerParser
