Class include other Class but with .nullish() or .optional() or .nullable()

[hepr]

My classes

export class ProductClass extends Z.class({
entityId: z.string(),
productId: z.string(),
productMain: z.string().nullable().optional(),
maxStockLevel: z.number().nullable().optional(),
minStockLevel: z.number().nullable().optional(),
stockTimeLimit: z.number().nullable().optional(),
sellAccount: z.string().toUpperCase().trim().nullable().optional(),
weight: z.number().min(0).default(0),
....
}) {
}

export class ProductInventoryLocationClass extends Z.class({
warehouseId: z.string(),
location: z.string(),
...
product: ProductClass.nullish(), // Crash with .nullish()
}) {

}

const productInventoryLocation = ProductInventoryLocationClass.parse(response)

Crash only when product field with .nullish() or .optional() or .nullable()

Thanks for reporting the error, I am able to reproduce it. Will fix.

[sam-goodwin]

I've managed to fix the parse error but can't add nullish because of weird type errors. Also noticed that nullable and optional no longer retain the class and will break your types. Perhaps a typescript compiler change has broken that.

I wouldn't recommend using this library because zod wasn't designed to be extended this way. Perhaps it'll be fixed in a later zod version.

Fixed in 0.0.15. But, I would also caution against using this library.
