Payment information is not entered

Error message

Payment information is not entered

What it means

Thrown in OpcConfirmOrder when GetProcessPaymentRequestAsync returns null (no payment info was staged) AND a payment workflow is required for the cart (line ~2062). This means the customer reached confirm-order without having entered payment information that the payment plugin staged via SetProcessPaymentRequestAsync.

Solutions

1. Ensure OpcSavePaymentInfo runs successfully and stages the ProcessPaymentRequest before confirm; redirect back to payment-info if GetProcessPaymentRequestAsync is null.
2. Verify session/temp-data persistence (configure distributed session like Redis/SQL Server in load-balanced deployments).
3. Confirm IsPaymentWorkflowRequiredAsync logic matches the cart total (zero-total carts should not require a workflow).

Example fix

// before
if (processPaymentRequest == null)
{
    if (await _orderProcessingService.IsPaymentWorkflowRequiredAsync(cart))
        throw new Exception("Payment information is not entered");
    processPaymentRequest = new ProcessPaymentRequest();
}

// after: redirect to payment-info instead of throwing
if (processPaymentRequest == null)
{
    if (await _orderProcessingService.IsPaymentWorkflowRequiredAsync(cart))
        return Json(new { error = 1, goto_section = "payment_info" });
    processPaymentRequest = new ProcessPaymentRequest();
}

var ppr = await _orderProcessingService.GetProcessPaymentRequestAsync();
if (ppr == null && await _orderProcessingService.IsPaymentWorkflowRequiredAsync(cart))
    return Json(new { error = 1, goto_section = "payment_info" });

catch (Exception exc) when (exc.Message == "Payment information is not entered")
{
    return Json(new { error = 1, goto_section = "payment_info" });
}

When it happens

Trigger: OpcSavePaymentInfo was skipped or failed silently so no ProcessPaymentRequest was stored in the session/temp data; the cart contains items requiring payment but no payment info was collected; session/temp storage was lost between steps.

Common situations: Customer back-navigated and skipped the payment-info step; the payment-info POST failed validation but the flow continued; in-memory session lost on app recycle; a free/zero-total flow was expected but IsPaymentWorkflowRequiredAsync still returned true due to misconfiguration.
