type: 'null' properties support in schemas

[peter-plochan]

Even it's not released yet, in OpenAPI 3.1 Specification, there will be support for the type: 'null' property within schemas (see also JSON Schema Draft 2019-09). It seems that the parser doesn't support this for now because using swagger-cli tool, the schema validation fails with the message:

Data does not match any schemas from 'oneOf' at #/paths//pets/{id}/put/requestBody/content/application/json/schema
      Data does not match any schemas from 'oneOf' at #/content/application/json/schema/properties/nullProp
        No enum match for: null at #/properties/nullProp/type
        Missing required property: $ref at #/properties/nullProp
      Missing required property: $ref at #/content/application/json/schema
    Missing required property: $ref at #/paths//pets/{id}/put/requestBody

I'm not sure how strict the parser (and its validation) would be, but it would be nice to support "null" type there. Thanks

Thanks for opening this ticket. There are several major changes in OpenAPI 3.1, and we're planning to start soon on supporting them all.

@JamesMessinger OpenApi 3.1 has been released and the schema is available at:
https://github.com/OAI/OpenAPI-Specification/tree/master/schemas/v3.1

Anything we can do to help ?
