Troubleshooting TS Error with Composed Schemas in TypeScript

const OptionFromEmptyString: S.Schema<Option.Option<string>, string> = S.transform(
  S.string,
  S.option(S.string),
  (a) => (a.length > 0 ? Option.some(a) : Option.none()),
  (a) => (a._tag === "Some" ? a.value : ""),
);

const FirstName = S.string.pipe(S.brand("Name"));

const MaybeFirstName = S.compose(OptionFromEmptyString, FirstName);
