PDF Invoice

-- HikaShop version -- : 6.6.0
-- Joomla version -- : 5.4.8
-- PHP version -- : 8.3.33
-- Browser(s) name and version -- : Firefox 155.0.1 and Chrome 152.0.7977.83

I installed PDF Invoice 5.0.5. When going to Hikashop > Orders, checking a single order, and clicking the Invoice button at the top, I receive a white screen the following error:

Undefined constant "Com\Tecnick\Pdf\Image\IMAGETYPE_SWC"

There is no logo path set in Hikashop configuration page. I have tried adding one to see if this would resolve the issue, but it does not. I am using the Default invoice layout. I have tried switching to various layouts, but each product this error.

Please advise.
