failed to cancel question batch

Error message

failed to cancel question batch: %w

What it means

CancelQuestionBatch POSTs to /workspaces/{id}/questions/cancel to cancel a pending question batch. This error wraps transport-level failures from c.post (connection refused, DNS, TLS, context cancellation), meaning the cancel request never reached the server and any pending question remains open.

Solutions

1. Check server reachability and retry CancelQuestionBatch; a false return simply means nothing was pending.
2. Verify client base URL/port configuration.
3. Use a fresh context with an adequate timeout if cancellations time out.
4. If the question was answered elsewhere, treat the cancel as moot and continue.

Example fix

// before
ok, err := client.CancelQuestionBatch(ctx, wsID)
if err != nil { panic(err) }
// after
ok, err := client.CancelQuestionBatch(ctx, wsID)
if err != nil {
	log.Warn("cancel request failed; question may still be pending", "err", err)
	return err
}
if !ok { log.Info("no pending question to cancel") }

if wsID == "" {
	return errors.New("workspace id is required to cancel a question batch")
}
if err := serverReachable(ctx, baseURL); err != nil {
	return fmt.Errorf("cannot cancel: %w", err)
}

ok, err := client.CancelQuestionBatch(ctx, wsID)
if err != nil {
	// non-fatal: question may have already been answered/cancelled elsewhere
	log.Warn("question cancel failed", "err", err)
	return nil
}
if !ok { log.Info("no pending question batch") }

When it happens

Trigger: Calling CancelQuestionBatch while the server is unreachable, the network drops, or the context is cancelled/timed out before the POST completes.

Common situations: Cancelling during a server restart; user aborting a prompt while offline; VPN/network transitions; wrong server address in client config.
