Using a reference in items of array results in error #464

Open pmhofman opened 1 year ago

pmhofman commented 1 year ago

When a reference is used in items: of an array, e.g. :

type: object
description: Model for response from call to GET products requiring an array of products to be returned.
title: GetProductResponse
properties:
  Products:
    type: array
    items:
      $ref: Product.yaml

and error is thrown while resolving the references:

$ java -jar openapi-diff-cli-2.1.0-beta.4-all.jar --error --fail-on-incompatible source/specification/openapi.yaml destination/specification/openapi.yaml
Unexpected exception. Reason: Invalid ref: ./common/models/Product.yaml
java.lang.IllegalArgumentException: Invalid ref: ./common/models/Product.yaml

Files GetProductResponse.yaml and Product.yaml both reside in the same directory.

Attachment contains the source and destination folders, which contain a copy of the same openapi spec. example.zip

@pmhofman Thanks for reporting this!

It looks like an issue with the reference resolution in the upstream project https://github.com/swagger-api/swagger-parser/.

Would you mind creating a bug report there and link it back to this issue?
