Should the Zod schema generator already support patternProperties?

[PatrickLehner-Kraken]

Hey everyone,

I'm trying to generate Zod schemas for an OAPI 3.1 doc with patternProperties, but the generated Zod schemas don't take the patternProperties into account. I can't find anything in the documentation or in existing issues or documentations about whether patternProperties is/should be supported, so I thought I'd ask here.

To illustrate, using the following minimal OAPI doc:

openapi: '3.1.0'
info:
  version: 1.0.0
  title: Swagger Petstore
servers:
  - url: http://petstore.swagger.io/v1
paths:
  /pets:
    get:
      summary: Info for a specific pet
      operationId: showPetById
      responses:
        '200':
          description: Expected response to a valid request
          content:
            application/json:
              schema:
                type: object
                patternProperties:
                  '^[a-zA-Z0-9]+$':
                    type: string

And this orval.config.mjs:

export default {
  'api-schema': {
    input: {
      target: './api.yaml',
    },
    output: {
      client: 'zod',
      mode: 'single',
      target: './zod-schema.ts',
    },
  },
};

Orval v7.11.2 generates the following zod-schema.ts:

/**
 * Generated by orval v7.11.2 🍺
 * Do not edit manually.
 * Swagger Petstore
 * OpenAPI spec version: 1.0.0
 */
import {
  z as zod
} from 'zod';

/**
 * @summary Info for a specific pet
 */
export const showPetByIdResponse = zod.object({

})

I expected showPetByIdResponse to be a schema like this:

export const showPetByIdResponse = zod.record(
  z.string().regex('^[a-zA-Z0-9]+$'),
  z.string()
);

@PatrickLehner-Kraken i think someone already reported your bug: #2277

Oh thanks, @melloware! I'll leave this discussion open for now because I don't know if the cause is the same, but it does look like it might be related!
