Hello everyone,

I have noticed that I cannot adjust the quantity in the shopping basket for a custom line item. When I adjust the quantity, I get the message:

**Unfortunately, something went wrong.**

At first I thought that I had configured the custom line item incorrectly, but I would be surprised if I had. To test this, I copied all the properties of another product for which the quantity adjustment works:

```auto
$cart = $this->cartService->getCart($context->getToken(), $context);
$first = $cart->getLineItems()->first();
$lineItem->setCover($first->getCover());
$lineItem->setDataContextHash($first->getDataContextHash());
$lineItem->setDataTimeStamp($first->getDataTimeStamp());
$lineItem->setDeliveryInformation($first->getDeliveryInformation());
...

```

However, the quantity adjustment does not work.

What could be the problem?

Best

Any idea what’s the problem here?
