Luxon DateTime with Yup and Typescript

[dro-sh]

I have a type Person:

import { DateTime } from "luxon";

type Person {
  name: string;
  birthDate: DateTime; // required property
}

I would like to validate birthDate using yup:

import * as yup from "yup";

const schema: yup.SchemaOf<Person> = yup.object({
  name: yup.string().required(),
  birthDate: yup.mixed<DateTime>().default(DateTime.utc()).required() // does not work
});

I try use mixed, but it returns error

The types of 'fields.birthDate' are incompatible between these types.
Type 'MixedSchema<DateTime, AnyObject, DateTime>' is not assignable to type 'ObjectSchemaOf<DateTime, never> | Lazy<ObjectSchemaOf<DateTime, never>, any>'.
Type 'MixedSchema<DateTime, AnyObject, DateTime>' is missing the following properties from type 'ObjectSchema<{ get: ObjectSchemaOf<(unit: keyof DateTime) => number, never> | Lazy<ObjectSchemaOf<(unit: keyof DateTime) => number, never>, any>; ... 71 more ...; toRelativeCalendar: ObjectSchemaOf<...> | Lazy<...>; }, AnyObject, TypeOfShape<...>, AssertsShape<...>>': fields, _sortErrors, _nodes, _excludedEdges, and 11 more.

How I can validate DateTime with yup?
