Unexpected error while deleting all except current: {e}

Error message

Unexpected error while deleting all except current: {e}

What it means

Thrown by delete_all_except_current: any exception from SessionQueue.delete_all_except_current(queue_id, user_id) is wrapped as a 500 with the cause embedded in the detail. Deletion touches more state than cancellation (rows are removed), so foreign-key or integrity problems in the queue store surface through this handler.

Solutions

1. Read the embedded exception message in detail for the specific DB/service failure
2. Pause the processor before bulk-deleting to avoid write contention
3. Validate queue_id exists before the call
4. Back up and run DB integrity checks / migrations if constraint errors recur

Example fix

// before: delete while processing
await fetch(`/api/v1/queue/${queueId}/delete_all_except_current`, {method: 'PUT'});
// after: pause first, then delete
await fetch(`/api/v1/queue/${queueId}/processor/pause`, {method: 'PUT'});
await fetch(`/api/v1/queue/${queueId}/delete_all_except_current`, {method: 'PUT'});

const q = await fetch(`/api/v1/queue/${queueId}`);
if (!q.ok) throw new Error(`Queue ${queueId} not found`);
await fetch(`/api/v1/queue/${queueId}/processor/pause`, {method:'PUT'}); // stop writes before delete

function isDeleteResult(v) { return v !== null && typeof v === 'object' && 'deleted' in v; }

try {
  const res = await fetch(`/api/v1/queue/${queueId}/delete_all_except_current`, {method:'PUT'});
  if (res.status === 500) throw new Error((await res.json()).detail);
  return await res.json();
} catch (e) { console.error('bulk delete failed:', e.message); }

When it happens

Trigger: PUT /{queue_id}/delete_all_except_current with a bad queue_id, DB constraint/foreign-key failure while deleting queue rows, or a service-layer error during bulk delete.

Common situations: Deleting while items are actively being written by the processor (contention); databases with orphaned references from interrupted upgrades; stale queue_id pointing at a nonexistent queue.
