Bug description

Omit recognition failed

Input

interface BaseElement {
    type: string;
    left: 0;
    top: 0;
}
export interface ImageElement extends Omit<BaseElement, 'type'> {
    type: 'image';
}

Expected output

// Generated by ts-to-zod
import { z } from 'zod';

const baseElementSchema = z.object({
    type: z.string(),
    left: z.literal(0),
    top: z.literal(0),
});

export const imageElementSchema = baseElementSchema.omit({ type: true }).extend({
    type: z.literal('image'),
});

Actual output

// Generated by ts-to-zod
import { z } from 'zod';

const baseElementSchema = z.object({
    type: z.string(),
    left: z.literal(0),
    top: z.literal(0),
});

Versions

• Typescript: v5.2.22
• Zod: v3.8.3

Hello,

As a potential workaround, this does work with a type:

type BaseElement = {
  type: string;
  left: 0;
  top: 0;
};

export type ImageElement = Omit<BaseElement, "type"> & {
  type: "image";
};
