Because findOneByNumber refers to OrderRepository method, which verify order is not on cart state. So we have a null value using repository method.

    public function findOneByNumber(string $number): ?OrderInterface
    {
        return $this->createQueryBuilder('o')
            ->andWhere('o.state != :state')
            ->andWhere('o.number = :number')
            ->setParameter('state', OrderInterface::STATE_CART)
            ->setParameter('number', $number)
            ->getQuery()
            ->getOneOrNullResult()
        ;
    }

So what is the reason the order is in cart state? Because in the moment of creating an invoice the checkout should be completed and the order shouldn't be in the cart state anymore. I guess, but I'm not sure, there is a difference with the moment of dispatching the event between state machine callback and the doctrine events.

At this moment the order state is new instead of cart in the database.

Assert::notNull($order, sprintf('Order with number "%s" does not exist.', $orderNumber));

/** @var InvoiceInterface|null $invoice */
$invoice = $this->invoiceRepository->findOneByOrder($order);

I wonder if it wouldn't be better to put this logic on the callback after create transition on sylius_order state machine 🤔

@GSadee yes it will make the same thing, but one issue will happen here if the Order has not been saved yet.
Here is an example :

$order = $this->orderFactory->createNew();
/* add product, address and select payment, shipping etc */
$this->stateMachineFactory
    ->get($order, OrderCheckoutTransitions::GRAPH)
    ->apply(OrderCheckoutTransitions::TRANSITION_COMPLETE)
;

The result will be an error on the InvoiceCreator because the doctrine query will fail finding the messaged order number.

To solve this, the InvoiceCreator could be reshaped to be a state machine callback, WDYT ?

I know it's a big change and it will make useless triggering the OrderPlaced event and it will require moving the PDF creation to the OrderPaymentPaid event.

I'm not sure if I correctly understand you, is there a problem with moving the callback to sylius_order state machine, in this implementation or in both cases? What is more, as you probably suggested changing the moment of generating an invoice PDF, IMO it is not possible, it should be generated during invoice generation after the order is placed, not payment paid.

During the @sylius_invoicing_plugin.event_producer.order_placed'->__invoke() the invoice creation is dispatched and cause the error I mentioned. To solve this error we can :

  1. remove the dispatch and simply call the service creating the Invoice with a new method signature for the class
    Sylius\InvoicingPlugin\Creator\InvoiceCreator

    From :

    public function __invoke(string $orderNumber, \DateTimeInterface $dateTime): void

    To:

    public function __invoke(OrderInterface $order, \DateTimeInterface $dateTime): void
// Maybe the argument `$dateTime` can be removed and we can use `$order->getCheckoutCompletedAt()` instead

  2. Move the PDF creation to another moment like when the PDF is sent payment_state === 'paid'

From my point of view the Invoice data stored in the database are the immutable data, the PDF is a view of this data.
