In Drupal 10.2 generated qrcode link return empty image

The main difference in behavior of generating qr image between drupal10.1 and drupal10.2 is that first not set Content-Length header and last one set Content-Length: 0. I believe it could be fixed in another way, but u could use my patch as temporary solution.

@bovver The patch #2 works with the full QR Code configuration and drupal 10.2.1, thanks.

Just experienced this issue on Drupal 10.2.2.

Bumping this issue to get a fix and new release. Thanks!

Patch #2 also solved the issue for us on 10.2.3.

Thanks for the patch. It's working on Drupal 10.2.4.
