Support for nullable types in OAS 3.1

[tomfrew]

The JSON Schema spec supports multiple values for types which allows a property to be nullable.
e.g.

type: object
properties:
  foo:
    type: [string, "null"]

When generating types with this openapi-codegen it results in a void type.

export type Thing = {
  foo?: void;
}

I realise this is differnt from OAS 3.0 where there was a separate nullable property. Does this lib support OAS 3.1?

Hi

Did you find a workaround for this ?

Thx

Indeed, we are not supporting OAS 3.1 (I was not expecting such a breaking change between 3.0 and 3.1…)

I need to document myself a bit more about what changes to see if we can support everything
