Asking for feedback on a TypeScript approach to extract properties from an object using 'Effect'

class GetContentArrayFromDomError extends Data.TaggedError(
  "GetContentArrayFromDomError"
)<{
  msg: string;
}> {}

export const getContentArrayFromDom = (dom: JSDOM) =>
  Effect.succeed(dom).pipe(
    Effect.map(Struct.get("window")),
    Effect.map(Struct.get("document")),
    Effect.map(Struct.get("body")),
    Effect.map(Struct.get("firstElementChild")),
    Effect.filterOrFail(
      Predicate.isNotNull,
      () =>
        new GetContentArrayFromDomError({ msg: "First element child is null" })
    ),
    Effect.map(Struct.get("children")),
    Effect.map((x) => Array.from(x))
  );
