Could just use MediaItemResponse right?

@Valid @RequestBody CreateMediaItemRequest request) {
try {
MediaItem items = MediaItemRequest.asMediaItem(request.getItem());
library.addMediaItem(items, librarian);
MediaItemResponse responseItem = MediaItemResponse.from(items);
Map<String, MediaItemResponse> response = Map.of("item", responseItem);

return ResponseEntity.ok(response);
} catch (IllegalArgumentException e) {
return ResponseEntity.badRequest().build();
}
}
