Issues with creating a schema with an opaque type

import * as S from "@effect/schema/Schema";

const _Person = S.struct({
  name: S.string,
  age: S.option(S.number),
});

interface Person extends S.Schema.To<typeof _Person> {}

// Re-declare the schema to create a schema with an opaque type
const Person: Schema.Schema<Person> = _Person;

Type 'Schema<{ readonly name: string; readonly age: { readonly _tag: "None"; } | { readonly _tag: "Some"; readonly value: number; }; }, { readonly name: string; readonly age: Option<number>; }>' is not assignable to type 'Schema<Person, Person>'.
  The types returned by '[TypeId].From(...)' are incompatible between these types.
    Type '{ readonly name: string; readonly age: { readonly _tag: "None"; } | { readonly _tag: "Some"; readonly value: number; }; }' is not assignable to type 'Person'.ts(2322)
