[zod-nestjs]: required fields in zod schema are optional in dto objects

[blahetal]

Hi,
considering the example

export const CatZ = extendApi(
  z.object({
    name: z.string(),
    age: z.number(),
    breed: z.string(),
  }),
  {
    title: 'Cat',
    description: 'A cat',
  }
);
export class CatDto extends createZodDto(CatZ) {}
var cat: CatDto;
cat.age <<<--- data type is age?: number

all fields in the schema are required but the dto has all fields optional. Why does createZodDto do it or how can I make createZodDto to keep required fields in dto?

Thanks,
Libor

I have the same issue I don't understand this behavior.

Probably you are missing "strict": true, setting in your tsconfig.json

just checked it and it is set :(

Looks like this could be fixed by #194

Looks like this is still broken. Everything is optional, which makes DTOs fairly pointless from a validation perspective.

Anyone found a solution for this? Starting to doubt using this package now.

solved it by adding :
"strictNullChecks": true,
in my tsconfig.json
