Content & configuration

Example Swagger/OpenAPI definition:

 properties:
        checkInDate:
          title: Date in ISO8201 format
          type: string
          format: date
          example: 2019-02-01

Describe the bug you’re encountering

Following the specification i should see correct example in UI "checkInDate": "2019-02-01" but instead i see "checkInDate": {}

In schema block i see: example: OrderedMap {}

Expected behavior

Correct property example in dto object in request body

"checkInDate": "2019-02-01"

For me it seems that the problem only occurs when a $ref is used

paths:
  /pet/{petId}:
    get:
      parameters:
        # does not work
        - $ref: components/parameters/date.yaml
        # does work
        - name: date
          in: query
          schema:
            title: Date
            type: string
            format: date
          examples:
            example1:
              value: 2022-10-12
      responses:
        '200':
          description: successful operation

components/parameters/date.yaml looks like:

name: date-ref
in: query
schema:
  title: Date
  type: string
  format: date
examples:
  example1:
    value: 2022-10-12

You need to add quotes around the example value:

type: string
format: date
example: '2019-02-01'   # <----

Without the quotes, the value is parsed as a YAML timestamp which is a different data type than string.

Quotes solution doesn’t work, please fix.
