Failed validating 'oneOf' in schema

[manchenkoff]

Hi, after updating to the latest release I had a strange error with schemas.

Swagger example

/couriers/{courierIdentifier}:
        get:
            description: 'description text'
            tags:
                - Couriers
            parameters:
                -   $ref: '#/components/parameters/courierIdentifierInPath'
            responses:
                200:
                    description: 'successful response'
                    content:
                        application/json:
                            schema:
                                $ref: 'definitions/couriers/get.yml#/responses/GetResponse'
                400:
                    $ref: '#/components/responses/CommonSuccessfulResponse'
                500:
                    $ref: '#/components/responses/CommonSuccessfulResponse'

Validation error

{'description': 'successful response', 'content': {'application/json': {'schema': {'$ref': 'definitions/couriers/get.yml#/responses/GetResponse', 'x-scope': ['file:///data/swagger.yml']}}}} is not valid under any of the given schemas

Failed validating 'oneOf' in schema['properties']['paths']['patternProperties']['^\\/']['patternProperties']['^(get|put|post|delete|options|head|patch|trace)$']['properties']['responses']['patternProperties']['^[1-5](?:\\d{2}|XX)$']:
    {'oneOf': [{'$ref': '#/definitions/Response'},
               {'$ref': '#/definitions/Reference'}]}

On instance['paths']['/couriers/{courierIdentifier}']['get']['responses']['200']:
    {'content': {'application/json': {'schema': {'$ref': 'definitions/couriers/get.yml#/responses/GetResponse',
                                                 'x-scope': ['file:///data/swagger.yml']}}},
     'description': 'successful response'}

But if I remove $ref parameter in schema description or change it to type: string it works fine.

Do you know any solutions? Thanks

This happens to me, too.

/become:
    get:
      operationId: become_user
      parameters:
      - description: Numeric identifier of the user to turn into.
        explode: false
        in: query
        name: id
        required: false
        schema:
          type: string
        style: simple

Error:

I have this issue as well. For now I have added openapi-spec-validator<0.3 in my project's requirements.txt to avoid this issue.

You're probably getting stuck on #126 - The easiest workaround is to make a very basic '#/components/schemas/simple and point all your refs to that; then it'll validate all your other schemata and tell you where the error is.

Also pinning down the package here... :-/

Does #129 helps?

It can be tried temporarily using:

pip install --force-reinstall git+https://github.com/JulienPalard/openapi-spec-validator@show-context
