Error message

${id} is not a valid user ID, or the user has no novels.
${id} 不是有效的用戶 ID，或者該用戶沒有小說作品。

What it means

InvalidParameterError thrown by getNSFWUserNovels after the authenticated /v1/user/novels call returns an empty novels array. Because auth already succeeded, an empty list means the user ID is wrong/deleted or the user genuinely has no novel works. The message is bilingual and names the offending id.

Solutions

1. Confirm the id matches the numeric segment of https://www.pixiv.net/users/{id}/novels.
2. Open the user's profile and verify they have a Novels tab with works.
3. If the ID came from a third-party link, double-check it is the pixiv user ID and not an artwork or series ID.
4. Retry after confirming the account still exists.

function isValidPixivUserId(id: string): boolean {
  return /^\d+$/.test(id) && id.length > 0;
}
// before fetching:
if (!isValidPixivUserId(id)) {
  // reject as invalid user ID
}

const hasNovels = (resp: { data?: { novels?: unknown[] } }): boolean =>
  Array.isArray(resp.data?.novels) && resp.data.novels.length > 0;

try {
  return await getNSFWUserNovels(id, fullContent, limit);
} catch (e) {
  if (e instanceof InvalidParameterError && /not a valid user ID/.test(e.message)) {
    // user has no novels or ID is wrong: show the bilingual hint, do not retry
  }
  throw e;
}

When it happens

Trigger: Passing a non-existent or deleted pixiv user ID; a valid user who has published zero novels; a user whose only works are filtered out server-side.

Common situations: Copied a pixiv illust-only user ID into a novels route; ID typo; user deleted all novels; numeric ID truncated during copy.
