The inferred type of <SchemaName> references an inaccessible this type. A type annotation is necessary.

I'm using Zod with NestJS and facing an issue when trying to declare properties as .nullish() or .nullable().

An example

import { z } from 'zod';

export const partnerSchema = z.object({
  projectName: z.string(),
  startDate: z.coerce.date(),
  projectDuration: z.number().nullish(),
});

This yields a TS2527 error.

I used this code snippet, but it didn’t raise any exceptions. This might be related to the TypeScript configuration or other factors. Could you provide a minimal reproduction?
