Swagger schema with oneOf with List of object is no generating sample response in UI

Hi,
The below swagger definition is not creating sample responses in the Swagger UI. 

I believe its due to usage of oneOf with List of objects. Please see the example below

 

"content": {
"application/json": {
"schema": {
"oneOf": [
{"$ref": "#dogs"},
{"$ref": "#cats"}

]
}
}
}

 

"dogs": {
"type": "array",
"items": {
"$ref": "#/animal"
}
},

 

"cats": {
"type": "array",
"items": {
"$ref": "#/animal"
}
}

 

"animal": {
"type": "object",
"properties": {
"breed": {
"type": "string"
}
}
}

    Hi sudha78,

     

    I'm not 100% sure on what you are trying to achieve, but here's a definition showing two flavours similar to above.

     

    openapi: 3.0.3
info:
  title: Simple Pets API
  description: |-
    This is a sample Pets API showcasing some `oneOf` scenarios
  version: 0.0.1
tags:
  - name: pets
    description: Everything about your Pets
paths:
  /pets:
    get:
      tags:
        - pets
      summary: Get pets from catalog
      description: Returns a list of pets found on the server
      operationId: getPets
      responses:
        '200':
          description: successful operation
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Pets'
  /animals:
    get:
      tags:
        - pets
      summary: Get pets from catalog
      description: Returns a list of pets found on the server
      operationId: getAnimals
      responses:
        '200':
          description: successful operation
          content:
            application/json:
              schema:
                oneOf: 
                  - $ref: '#/components/schemas/Cat1'
                  - $ref: '#/components/schemas/Dog1'            
components:
  schemas:
    Dog:
      type: object
      properties:
        barks:
          type: boolean
          example: true
        likesFetch:

          example: true

    Animal:
      type: object
      properties:
        breed:
          type: string
          example: poodle

      Hi frankkilcommins 

      Thanks for your reply.

      The swagger definition is fine, but the problem is Response Sample(using ReDoc) is not generated for definition
      1) The problem am facing for path '/pets' is, the 'Response Sample'  is generated only for first option 'Cat1' and not generated for 'Dog1'

      2) For path '/animal', There is no Response sample generated for either 'Cat' or 'Dog'

    Hi sudha78,

     

    You're welcome. As far as I can tell both definitions are rendering fine (with and without examples) via SwaggerUI. You can try by importing either of the following into https://editor-next.swagger.io (File > Import URL):

     

    https://raw.githubusercontent.com/frankkilcommins/OAS-Examples/main/OAS3_0/oneOf-simple-withexample.yaml

     

    https://raw.githubusercontent.com/frankkilcommins/OAS-Examples/main/OAS3_0/oneOf-simple-noexample.yaml

     

    If your problem is purely with ReDoc, then head over to https://github.com/Redocly/redoc and register and issue. They do have some open issues regarding multiple oneOf rendering.
