Hi
When I am trying to download a „Cancellation bill“ from admin order details I am getting the following error and the file is not downloading
`{"errors":[{"status":"400","code":"DOCUMENT__GENERATION_ERROR","title":"Bad Request","detail":"Unable to generate document. Only versioned orders can be used for document generation.","meta":{"parameters":[]}}]}`
What does that mean? How to download the file?

It is a Shopware bug and the fix is available only in 6.4.0.0 which we cannot use in production.

So please edit the core file vendor/shopware/core/Checkout/Document/DocumentService.php
Replace the file function validateVersion with the following content
```
private function validateVersion(DocumentEntity $document, Context $context): void
{
if ($document->getOrderVersionId() === Defaults::LIVE_VERSION) {
// Only versioned orders can be used for document generation.
$orderVersionId = $this->orderRepository->createVersion($document->getOrderId(), $context);
$document->setOrderVersionId($orderVersionId);
$this->documentRepository->update(
[
[
'id' => $document->getId(),
'orderVersionId' => $orderVersionId,
],
],
$context
);
}
}
and also replace its function call with $this->validateVersion($document, $context);
```
There is no other solution for live site users. This is not good at all!
