Solutions

1. Check the wrapped message for the failing step
2. Verify storage state consistency afterwards (favorites vs categories) and repair if partial
3. Retry the delete after confirming the category still exists

const isFavoriteStorageError = (e: unknown): e is FavoriteStorageError => e instanceof FavoriteStorageError;

try { await manager.deleteCategory(id); } catch (e) { if (isFavoriteStorageError(e)) { /* verify favorites/categories consistency, then recover */ } throw e; }

When it happens

Trigger: Either updateData call fails (quota, I/O, provider error) during deletion; partial failure can occur after favorites were already unlinked.

Common situations: Storage failures mid-operation; provider timeouts; interrupted mobile app storage calls.
