You can't void this order

Error message

You can't void this order

What it means

Thrown by OrderProcessingService.VoidOfflineAsync when CanVoidOffline(order) returns false. An offline void is allowed only when OrderTotal > 0 and PaymentStatus == Authorized. It does not consult the payment gateway, so it only checks that the order is in an authorized (not yet captured) state with a non-zero total.

Solutions

1. Guard with: if (!_orderProcessingService.CanVoidOffline(order)) return; and report the reason.
2. Verify PaymentStatus == Authorized before enabling Void; if Paid, use Refund/RefundOffline instead.
3. For zero-total orders, void is not applicable.
4. Disable the Void UI action once the order leaves Authorized status.

Example fix

// before
await _orderProcessingService.VoidOfflineAsync(order);

// after
if (!_orderProcessingService.CanVoidOffline(order))
    return;

await _orderProcessingService.VoidOfflineAsync(order);

if (!_orderProcessingService.CanVoidOffline(order))
    return;

await _orderProcessingService.VoidOfflineAsync(order);

When it happens

Trigger: Calling VoidOfflineAsync when: OrderTotal == 0; or PaymentStatus != Authorized (Paid, Voided, Refunded, Pending). Common when an admin voids an order that was already captured (Paid) or already voided.

Common situations: Order already Paid (funds captured) so an offline void is invalid; order Pending (not authorized); order already voided; zero-total order.
