Error message

shop::app.products.booking.cart.integrity.event.ticket_sold_out

What it means

Webkul\Product\Exceptions\InsufficientProductInventoryException with the sold-out message from Booking::prepareForCart(), event branch. When isSlotAvailable() fails for a cart line and the Event helper's getAvailableTicketQuantity() returns 0, the code takes the 'ticket_sold_out' variant with the :ticket placeholder, telling the customer that the named ticket tier has no units left at all.

Solutions

Choose a different ticket tier that still has availability, or remove the sold-out line from the cart
Refresh the event page to see current per-tier availability
Raise the tier's qty cap or add a new tier in the booking product admin
Catch InsufficientProductInventoryException and display getMessage() so the customer learns which tier sold out

Example fix

// before
$cartProducts = $product->getTypeInstance()->prepareForCart($data);

// after
try {
    $cartProducts = $product->getTypeInstance()->prepareForCart($data);
} catch (\Webkul\Product\Exceptions\InsufficientProductInventoryException $e) {
    return back()->withErrors($e->getMessage()); // "General ticket is sold out"
}

Defensive patterns

Strategy: try-catch

Validate before calling

// Pre-check tier availability before add-to-cart
$typeHelper = app(\Webkul\BookingProduct\Helpers\Event::class);
$available = $typeHelper->getAvailableTicketQuantity($product);

if ($available <= 0) {
    return back()->withErrors('This ticket tier is sold out.');
}

Try / catch

try {
    $cartProducts = $product->getTypeInstance()->prepareForCart($data);
} catch (\Webkul\Product\Exceptions\InsufficientProductInventoryException $e) {
    return back()->withErrors($e->getMessage()); // '<ticket> is sold out'
}

Prevention

Mark sold-out tiers as disabled on the product page as soon as qty hits 0
Clean up test/failed orders so they don't consume ticket caps
For multi-tier events, keep fallback messaging that suggests other tiers
Treat a 0-availability read as authoritative only under the same transaction as add-to-cart

When it happens

Trigger: Add-to-cart on an event booking where the requested ticket tier's remaining quantity is exactly 0 (cap fully sold) - e.g. adding a 'General' ticket after the last one was ordered moments ago, while other tiers may still have stock.

Common situations: Ticket tier exhausted between page load and add-to-cart (race at the last unit); admin test orders consuming the full cap; customer re-submitting an old form for a tier that sold out; leftover carts holding the final units at checkout.
