openapi-parser: Unsupported OpenAPI version: 3.0.4

[jnv]

Ideally I'd raise this issue against openapi-parser repo, but it doesn't have issues enabled, so I report it here.

Steps to reproduce

Create the following files:

package.json

{
  "name": "repro",
  "version": "1.0.0",
  "type": "module",
  "dependencies": {
    "oas": "^25.2.1",
    "oas-normalize": "^12.0.0"
  }
}

// index.js
import OASNormalize from 'oas-normalize';

const yaml = `
openapi: 3.0.4
info:
  version: 1.0.0
  title: Petstore simple w/o tags
servers:
  - url: https://httpbin.org
paths:
  '/pet/{id}':
    parameters:
      - name: id
        in: path
        required: true
        schema:
          type: integer
    get:
      summary: Find a pet
      description: This operation will find a pet in the database.
      responses:
        '400':
          description: Invalid status value
      security: []
`;

const oas = new OASNormalize(yaml);
const definition = await oas.validate();

Install and run:

npm install
node index.js

Expected result

The script would run without any issues.

Actual result

The script crashes with error:

SyntaxError: Unsupported OpenAPI version: 3.0.4. Swagger Parser only supports versions 3.0.0, 3.0.1, 3.0.2, 3.0.3, 3.1.0

Notes

Support for the latest minor versions of OAS was quite recently fixed in the upstream openapi-parser: APIDevTools/swagger-parser#264

Since there are no functional changes in the latest versions, it's really only about adding support for the newer versions.

As a very ugly workaround, I can (sometimes) modify the OAS before parsing, e.g. for the example above:

// yaml = ...
const fixedYaml = yaml.replace(/^openapi:\s*3\.0\.4/m, 'openapi: 3.0.3');

const oas = new OASNormalize(fixedYaml);
const definition = await oas.validate();
