Getting an error when I publish a course to HikaShop

I am getting an error when I publish a new course into HikaShop. If I go to Joomdle->Shop and publish the new course, I get this error:

An error has occurred.
0 count(): Argument #1 ($value) must be of type Countable|array, null given

However the course looks to be set up properly in HikaShop. Or at least it appears to work. Any ideas what the issue might be or how to fix it?

Joomla 5.0.3
Joomdle 2.2.3
HikaShop 5.0.3
Moodle 4.1.6 (Build: 20231009)
PHP 8.1.27

Thanks for the bug report, it is a warning caused by an uninitialized variable.

I will release a new version soon. If you want to fix it before, you just need to edit file plugins/joomdleshop/joomdleshophikashop/joomdleshophikashop.php and add this in line 155:
$element->images = array ();

Just an FYI that this error still exists. I am creating a new Joomla/Joomdle/Moodle instance and ran into it again using the latest downloads from your website. Might want to ensure that the fix gets added to the plugin.

Thanks for the reminder, I forgot about this one.
I have published it now for download, although you won't see it pop up in updates yet, because I am having some issues with that and I cannot work on it right now.

On this topic when I want to publish or unpublish a course I get the following error:

An error has occurred.
0 Call to undefined method Joomla\Database\Mysqli\MysqliDriver::query()

Joomla 5.2.2 and moodle 4.5.2

I downloaded the new plugin and that seems to have resolved the matter
