Is it possible to fallback all schema fields recursively?

[tal-rofe]

Given a schema, of any type you can think of, I want to fallback any error to null value.

That means, given this schema:

import { z } from "zod";

const schemaExample = z.object({
  x1: z.object({
    x2: z.object({
      x3: z.object({
        x4: z.number(),
      })
    })
  })
})

and given this code:

const objectExample = {
  x1: {
    x2: {
      x3: {
        x4: "ewfsd"
      }
    }
  }
}

console.log(schemaExample.parse(objectExample));

The console result should be

const objectExample = {
  x1: {
    x2: {
      x3: {
        x4: null
      }
    }
  }
}

Because x4 should be of type number but was wrong type, therefore "fallbacked" to null value. Of course I could do:

const schemaExample = z.object({
  x1: z.object({
    x2: z.object({
      x3: z.object({
        x4: z.number().nullable().catch(null),
      })
    })
  })
})

But I want this .nullable().catch() on any field recursively and it makes the code ugly. Any suggestion? it also should be valid for arrays, actually anything. Array example: z.array(z.string()) and array [1, "x", "y"] should be transformed to [null, "x", "y"]
