Schema referenced in patternProperties is not embedded in bundled file

[arvidfm]

Describe the bug
References to schemas defined in external files do not get embedded in components if present in a patternProperties definition of an object. Instead, the $ref still points to the external file even after bundling.

To Reproduce
Steps to reproduce the behavior:

1. Given this .redocly.yaml file

apis:
  main@v1:
    root: openapi/openapi.yaml

2. And these OpenAPI files

openapi/openapi.yaml

openapi: 3.1.0
info:
  title: Test
  version: 1.0.0
paths:
  /asset/{assetId}:
    get:
      operationId: assetGetAsset
      summary: Fetch an asset
      requestBody:
        content:
          application/json:
            schema:
              type: object
              patternProperties:
                .*:
                  $ref: object.yaml

openapi/object.yaml

type: object
properties:
  id:
    type: integer

3. Run this command with these arguments... openapi bundle -o dist
4. See error

The resulting dist.yaml contains:

openapi: 3.1.0
info:
  title: Test
  version: 1.0.0
paths:
  /asset/{assetId}:
    get:
      operationId: assetGetAsset
      summary: Fetch an asset
      requestBody:
        content:
          application/json:
            schema:
              type: object
              patternProperties:
                .*:
                  $ref: object.yaml
components: {}

Note how the reference to object.yaml is still there.

Expected behavior
The referenced schema should be embedded, something like:

openapi: 3.1.0
info:
  title: Test
  version: 1.0.0
paths:
  /asset/{assetId}:
    get:
      operationId: assetGetAsset
      summary: Fetch an asset
      requestBody:
        content:
          application/json:
            schema:
              type: object
              patternProperties:
                .*:
                  $ref: '#/components/schemas/object'
components:
  schemas:
    object:
      type: object
      properties:
        id:
          type: integer

Thank you for reporting this @arvidfm!

However, this is not a bug but rather an enhancement as we don't support patternProperties yet 🙂

BTW, in your exact case you can use additionalProperties instead of patternProperties:

additionalProperties:
  $ref: object.yaml

[amiika]

This is still an issue. Tried to use $ref under patternProperties but it is not working.

Example:

title: Facts
type: object
description: A set of financial facts in xBRL-JSON format.
properties:
  facts:
    patternProperties:
      "^[a-zA-Z0-9_-]+$":
          properties:
            value:
              type: string
              example: '12223000'
            decimals:
              type: integer
              example: -3
            dimensions:
              $ref: './Dimensions.yaml'
          required:
            - value
            - dimensions
          example: shtag_10414

@amiika yes, this is still to be implemented. Maybe you can try using additionalProperties instead? Is there a way to restrict the names of the properties other than using JSON schema for your case?

[kevin-lithic]

@tatomyr do you know if this is something that will be supported soon?

[tatomyr]

The fix is coming through. Thanks, @kevin-lithic, for bringing it to my attention!
