Solutions

  1. Read error.cause for the root failure
  2. Free storage space / prune unused tags
  3. Retry once for transient provider errors
Defensive patterns

Strategy: retry

Type guard

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

Try / catch

try { await manager.addTag(t); } catch (e) { if (isFavoriteStorageError(e) && isTransient(e.cause)) await manager.addTag(t); else throw e; }

Prevention

When it happens

Trigger: storageProvider.updateData(TAGS, ...) throwing quota/I/O/serialization errors while inserting a new tag.

Common situations: Storage quota exhausted from many tags; provider write failures; concurrent tag writes colliding.
