The openId Connect dows not work with openapi3 and swagger.

info:
  description: "This is a sample."
  version: "1.0.0"
  title: "Swagger Petstore"
paths:
  /pet:

Describe the bug you're encountering

When I click authorize and select the last option in the authorization options, I get an error.

Authorization Error
Error 400: invalid_request
Required parameter is missing: response_type

To reproduce...

Steps to reproduce the behavior:

1. Go to https://editor.swagger.io/
2. Paste the above config
3. Click authorize
4. Select the last authorization option with all scopes
5. See the error message

Expected behavior

Minimal openapi3 config with openid connect authentication should allow login.

Additional context or thoughts

Is there a way to set the response_type some how? Maybe this is only a documentation issue.

Start by reproducing the OpenAPI 3 configuration in the Swagger Editor and tracing the Swagger UI authorize flow for the openIdConnect security scheme. Confirm where the authorization request is assembled; done means the request includes response_type and the documented minimal configuration allows login without the reported error.
