Zod V4 fallback

Did anyone already tried Zod V4 with Tanstack router search params?

I have this search params object

export const GroupsRequest = GroupsFilters.extend({
  pageNumber: fallback(number().positive(), 1).default(1),
  pageSize: fallback(number().positive(), 20).default(20),
  column: fallback(ZodEnum(columns), columns[0]).default(columns[0]),
  desc: fallback(boolean(), true).default(true),
})

export const GroupsRequest = GroupsFilters.extend({
  pageNumber: fallback(number().positive(), 1).default(1),
  pageSize: fallback(number().positive(), 20).default(20),
  column: fallback(ZodEnum(columns), columns[0]).default(columns[0]),
  desc: fallback(boolean(), true).default(true),
})

Where Typescript is throwing an error

Argument of type 'ZodNumber' is not assignable to parameter of type 'ZodTypeAny'.

Argument of type 'ZodNumber' is not assignable to parameter of type 'ZodTypeAny'.

This works perfectly fine with Zod V3.
