Failed to rename tag

Error message

Failed to rename tag: ${errorMessage}

What it means

FavoriteStorageError thrown by renameTag when any step of the rename (updating the tag library, rewriting favorites' tag arrays, or updateStats) fails with a non-FavoriteError.

Solutions

1. Check the wrapped message to identify which write failed
2. Verify favorite records' tags fields are arrays of strings
3. Retry after freeing storage; use updateStats sparingly to avoid extra writes

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

try { return await manager.renameTag(oldTag, newTag); } catch (e) { if (isFavoriteStorageError(e)) { /* verify tag library consistency before retry */ } throw e; }

When it happens

Trigger: Any updateData/put failure during the multi-write rename; favorites containing malformed tag arrays causing the rewrite to throw.

Common situations: Quota exceeded while rewriting many favorites; storage provider failures mid-rename; corrupted favorite records.
