Solutions

1. Reload categories and let the user re-pick a valid one
2. Catch FavoriteCategoryNotFoundError and reset the form's category selection
3. Verify categoryId is set from a fresh fetch, not hardcoded
4. Recreate missing categories or map to a fallback category before insert

Example fix

// before
await mgr.addFavorite({ ...fav, categoryId });
// after
const cats = await mgr.getCategories();
if (!cats.some(c => c.id === categoryId)) categoryId = cats[0]?.id;
await mgr.addFavorite({ ...fav, categoryId });

const cats = await mgr.getCategories();
if (!cats.some(c => c.id === categoryId)) categoryId = cats[0]?.id;

const isCategoryNotFound = (e: unknown): e is FavoriteCategoryNotFoundError => e instanceof FavoriteCategoryNotFoundError;

try { await mgr.addFavorite(payload); } catch (e) { if (isCategoryNotFound(e)) { await refreshCategories(); return retryWithFreshCategory(); } throw e; }

When it happens

Trigger: addFavorite/updateFavorite with a categoryId that was deleted, or category operations on a stale category id, via the Electron proxy.

Common situations: Category deleted in another window while a form was open; stale category list in UI state; default category removed by user; migration dropped old categories.
