Usage of `allOf` generates an incomplete type

What are the steps to reproduce this issue?

1. Clone your repo
2. yarn install and yarn build on the root
3. cd samples/basic/ && yarn install and modify the petstore.yaml
4. Generate the model using yarn example

What happens?

The generated models look like this:

petBase.ts

/*
 * Generated by orval v5.5.3 🍺
 * Do not edit manually.
 * Swagger Petstore
 * OpenAPI spec version: 1.0.0
 */

export interface PetBase {
  id: number;
  name: string;
  tag?: string;
}

pet.ts

/*
 * Generated by orval v5.5.3 🍺
 * Do not edit manually.
 * Swagger Petstore
 * OpenAPI spec version: 1.0.0
 */
import type { PetBase } from './petBase';

export type Pet = PetBase;

What were you expecting to happen?

I would expect Pet to contain all fields of PetBase and the new color property like this:

pet.ts

/*
 * Generated by orval v5.5.3 🍺
 * Do not edit manually.
 * Swagger Petstore
 * OpenAPI spec version: 1.0.0
 */
import type { PetBase } from './petBase';

export interface Pet extends PetBase {
  color: string;
}
// OR
export type Pet = PetBase & { color: string; };

Hey @anymaniax, ok I understood my mistake, it was a syntax issue. I should specify it like:

    Pet:
      allOf:
        - $ref: '#/components/schemas/PetBase'
        - type: object <-- HERE
          required:
            - id
            - name
          properties:
            color:
              type: string

TBH, I would like to migrate from openapi generator. In openapi, the generation was working even with the wrong syntax:

export interface Pet {
  id: number;
  name: string;
  tag?: string;
  color: string;
}

I’ll fix my specs, thank you 😉
