[zod-nestjs] createZodDto with optional

[af-lsh]

Hey, I'm trying to create a DTO with optional properties. Simple setup:

export const testSchema = z.object({
  field: z.string().optional(),
  another: z.string(),
});

export class TestDto extends createZodDto(testSchema) {}

However it fails with:

TS2509: Base constructor return type '{ [k in keyof addQuestionMarks<baseObjectOutputType<{ field: ZodOptional<this>; another: ZodString; }>, any>]: addQuestionMarks<baseObjectOutputType<{ field: ZodOptional<...>; another: ZodString; }>, any>[k]; }' is not an object type or intersection of object types with statically known members.
    27 | });
    28 |
  > 29 | export class TestDto extends createZodDto(testSchema) {}

I feel like this would be very basic and common use case. So I wonder what could be wrong on my side?
I followed the instructions of https://github.com/wahyubucil/nestjs-zod-openapi/ to set things up.

Thanks :)

So I just figured out I could use field: z.optional(z.string()) and it works like expected 👍
Maybe someone could still check if the other way is working somehow?
