FAVORITE_NOT_FOUND

Error message

${error.id}

What it means

The Electron main process returned an IPC error with code FAVORITE_NOT_FOUND; the renderer proxy converts it to FavoriteNotFoundError carrying the favorite id. It means no favorite prompt with that id exists in storage (or it was deleted).

Solutions

1. Refresh the favorites list and retry with a current id
2. Catch FavoriteNotFoundError and remove the stale entry from UI state
3. Verify the id is passed unchanged (no trimming/encoding issues)
4. Check the favorite wasn't deleted by sync/import in another process

Example fix

// before
await favoriteManager.getFavorite(id);
// after
try { return await favoriteManager.getFavorite(id); }
catch (e) { if (e instanceof FavoriteNotFoundError) return null; throw e; }

const exists = (await mgr.getFavorites()).some(f => f.id === id);

const isFavoriteNotFound = (e: unknown): e is FavoriteNotFoundError => e instanceof FavoriteNotFoundError;

try { return await mgr.getFavorite(id); } catch (e) { if (isFavoriteNotFound(e)) return null; throw e; }

When it happens

Trigger: Calling getFavorite/updateFavorite/setFavoritePromptAssetCurrentVersion/deleteFavoritePromptAssetVersion with a stale or nonexistent favorite id via the Electron proxy.

Common situations: UI holding a cached id after the favorite was removed on another window/device; deleted favorite still open in an editor; race between list refresh and delete; id typo or truncated id.
