Failed to get settings snapshots

Error message

Failed to get settings snapshots

What it means

Thrown by `getSnapshots` after POST `/api/settings/get-snapshots` returns a non-ok response. Notably the catch returns `[]`, so callers receive an empty list rather than seeing the error. The request uses `omitContentType: true`.

Solutions

1. Confirm `/api/settings/get-snapshots` is registered and returns 200.
2. Check server logs since the empty-array fallback hides the real error.
3. Verify session validity and directory permissions.

Example fix

// before
const snaps = await getSnapshots(); // silent [] on error
// after
const r = await fetch('/api/settings/get-snapshots', { method: 'POST', headers: getRequestHeaders({ omitContentType: true }) });
if (!r.ok) console.error('snapshots failed', await r.json());

let snaps = []; try { snaps = await getSnapshots(); } catch (e) { console.error(e); }

When it happens

Trigger: Backend endpoint error; permissions denied on the snapshots directory; session expired; misconfigured content-type header rejected by middleware.

Common situations: Snapshots feature disabled or misconfigured; deployment where the endpoint is not registered; silent failure mistaken for 'no snapshots'.
