Error with Hikaserial on PHP 8

-- HikaShop version -- : 4.4.2
-- HikaSerial version -- : 3.1.2
-- Joomla version -- : 3.9.27
-- PHP version -- : 8.0.4

Hello,
i suppose Hikaserial is not yet compatible but it could be really good if it will cause we saw a significative improvement with speed.
Here is a video on our dev version :
www.loom.com/share/4317d8ba3f7a4b83b50acd96c78eca3d
Error : Fatal error: Array and string offset access syntax with curly braces is no longer supported in xxxxxxx/administrator/components/com_hikaserial/inc/tcpdf/tcpdf.php on line 11379
This error is showed on administrator also when we try to dowload the pdf file.
Do you think it could be fixed ?
Thanks !
Olivier

Hello,

The error you have is related to the TCPDF library that is include in HikaSerial package.
While HikaSerial is using the library version 6.2.12 ; it is possible that a newer version would fix the issue if they worked on the PHP8 compatibility.

Hello Jérôme.
Thanks !
I confirm it works, i replaced the library located on
/public_html/administrator/components/com_hikaserial/inc/tcpdf by the new one and now it works without problem.
Thanks !
