Solutions

Check the appended errorMessage for the storage root cause
Verify writability and initialization of the storage provider
Retry after resolving transient storage contention

Defensive patterns

Strategy: try-catch

Try / catch

try { await manager.setFavoritePromptAssetCurrentVersion(id, versionId); }
catch (e) {
  if (e instanceof FavoriteStorageError) { /* surface storage failure */ }
  else throw e;
}

Prevention

Ensure storage is initialized and writable before version switches
Back up favorites storage before batch version operations

When it happens

Trigger: storageProvider.updateData or updateStats throwing (write failure, permissions, quota, serialization) during a version switch.

Common situations: Backing store unwritable or locked; interrupted write leaving the store inconsistent; custom provider throwing raw errors.
