Failed to initialize API storage, falling back to file stora

Error message

Failed to initialize API storage, falling back to file storage:

What it means

StorageFactory.createWithFallback() tries API-backed storage first; if creating or initializing it throws, it logs this warning (with the error) and falls back to local file storage, so the app keeps working but without the remote store.

Solutions

Inspect the logged error object for the root cause (auth vs network vs config)
Verify API credentials and base URL in the storage config; test the endpoint with curl
Fix network/firewall issues so the API endpoint is reachable
Accept the file-storage fallback knowingly, or explicitly choose file storage to silence the warning

Example fix

// before
const storage = await StorageFactory.createWithFallback(config); // silently uses file storage
// after
const storage = await StorageFactory.createWithFallback(config);
if (storage.type !== 'api') console.warn('Running on file storage fallback; API storage failed to initialize');

Defensive patterns

Strategy: fallback

Validate before calling

const reachable = await fetch(`${config.apiBaseUrl}/health`, { method: 'HEAD' }).then(r => r.ok).catch(() => false);
if (!reachable) console.warn('API unreachable; expect file-storage fallback');

Try / catch

const storage = await StorageFactory.createWithFallback(config);
if (storage.constructor.name !== 'ApiStorage') {
  logger.warn('Proceeding with file storage; API storage init failed — check credentials/network');
}

Prevention

Verify API base URL and token in config before startup
Add a health-check ping to the storage API in deployment checks
Decide explicitly whether file-storage fallback is acceptable for your environment
Monitor logs for this warning to detect silent fallbacks

When it happens

Trigger: createWithFallback() invoked when API storage cannot be created/initialized — unreachable API endpoint, invalid/missing auth credentials in config, unsupported config shape, or network failure during initialize().

Common situations: Offline development machine, wrong API base URL or expired token in config, API server down during deploy, firewall blocking the endpoint in CI.
