Content & configuration

Example OpenAPI definition:

openapi: 3.0.2
info:
  title: 'Test'
  version: 1.0.0

paths:
  /test:
    get:
      responses:
        '200':
          description: 'OK'
          content:
            application/json:
              schema:
                type: array
                items:
                  type: integer
                minItems: 3
                maxItems: 5

Describe the bug you're encountering

The Swagger Editor is ignoring the minItems attribute of an array-type response when auto-generating example values. Currently, only one item is being generated regardless of the minItems declaration in the schema.

To reproduce...

Steps to reproduce the behavior:

1. Create a new API specification
2. Copy/paste the minimum example in this issue
3. Refer to the right-panel with the API preview
4. Open the /test endpoint path and verify the example value being generated for the response

Expected behavior

Auto-generated example value showing at least minItems elements in the array. For the example in this issue, it should be showing something like this: [0, 0, 0].

Just verified it also happens in the live Swagger Editor: http://editor.swagger.io/

Got the same issue. It makes one have to manually add the missing values which slows down the work. Any updates on the issue?

[hhromic]

Thanks @GregNed for reminding me of this issue.

I can confirm that both, the latest Docker image and the online version of the Swagger Editor both seem to have fixed the issue:

I can also confirm that the latest Docker Image of the Swagger UI also is fixed 👍

@GregNed maybe try updating your local Swagger component to latest?

[GregNed]

@hhromic Alright, let's close it then. I'm using it via the Connexion lib for Python. I guess they just haven't updated their dependencies yet.

@GregNed looks like you are not alone: spec-first/connexion#1412
And looks like a PR to update Swagger UI is already proposed so I guess you just have to wait :)
