Schema for picked and nullabled type is not nullable

[t-animal]

Bug description

When picking a subtype and marking it nullable, the generated zod schema loses the nullable attribute

Input

export type foo = {
        bar: number;
}

export type bla = foo['bar'] | null

Expected output

export const blaSchema = fooSchema.shape.bar.nullable();

Actual output

export const blaSchema = fooSchema.shape.bar

Versions

• Typescript: 4.9.3
• Zod: 3.21.4

Hey, I guess you did a mistake writing the issue since the "Expected output" and "Actual output" are identical.

But running it locally, I can see than the actual output is the following:

export const fooSchema = z.object({
  bar: z.number(),
});

export const blaSchema = fooSchema.shape.bar;

Good catch!

Yes, sorry. I have updated the issue.
