“nullable” reference objects are not correctly generated.

The issue is that when I have a type like this:

const personSchema = z.object({
   firstname: z.string(),
   lastname: z.string()
});

const houseSchema = object({
   address: z.string(),
   owner: personSchema.nullable().optional()
});

When the open API spec is generated the owner field is generated like:

"owner": {
  "oneOf": [
    {
      "$ref": "#/components/schemas/Person"
    },
    {
      "nullable": true
    }
  ]
},

But it is incorrect, as when the client uses the spect to generate the typescript code, the owner field is not well recognized. The correct output should be:

"owner": {
  "oneOf": [
    {
      "$ref": "#/components/schemas/Person"
    },
  ],
  "nullable": true
},

Ah nice one.

TIL: OAI/OpenAPI-Specification#1368

I'll raise a PR sometime todayish

Great, thank you so much,

FYI: in my case, this format I've shown you works perfectly using "anyOf", "oneOf" and "allOf". Check this screenshot of the swagger editor using "anyOf":
