Error message

Failed to get queue item summaries

What it means

Catch-all in get_queue_item_summaries_by_ids: any exception from fetching summaries or sanitizing them per-user becomes a 500 with the static detail 'Failed to get queue item summaries'. As with error 144 the client gets no cause information; diagnostics require server logs.

Solutions

1. Look at the server-side traceback for the real exception
2. Verify ids exist and belong to the given queue before batching the request
3. If multiuser is on, inspect stored summaries for schema drift and repair/upgrade the DB
4. Retry; treat as transient if it coincides with heavy DB activity

const ids = await (await fetch(`/api/v1/queue/${queueId}/item_ids`)).json();
if (requestedIds.some(id => !ids.includes(id))) console.warn('some ids may have been deleted; summary fetch may fail');

function isSummaryList(v) { return Array.isArray(v) && v.every(s => s && typeof s === 'object' && 'item_id' in s && 'status' in s); }

try {
  const res = await fetch(`/api/v1/queue/${queueId}/item_summaries_by_ids`, {method:'POST', headers:{'Content-Type':'application/json'}, body: JSON.stringify({item_ids: requestedIds})});
  if (!res.ok) return [];
  return await res.json();
} catch { return []; }

When it happens

Trigger: POST /{queue_id}/item_summaries_by_ids when the queue service throws - unknown queue_id, DB failure, or sanitize_queue_item_for_user failing on a stored summary with unexpected shape.

Common situations: Requesting summaries for ids deleted moments earlier; mixed-version clients sending ids from a prior schema; multiuser mode where sanitizer input is malformed.
