I can access to Component->MailJet->Preferences
But no way on

Hi,

Potential FIX for this:

1. Make sure you can write to the directory /joomla/administrator/components/com_mailjet/lib/lib/
2. Edit /joomla/administrator/components/com_mailjet/lib/lib/mailjet-api-helper.php
3. Add the line 'use Joomla\CMS\Factory;' after the comment section at the top (line 11 or 12). Make sure it is before the line 'defined('_JEXEC') or die('Restricted access');'
4. Save the file
5. That fixed it for me.

I have the same issue with Joomla 5.1.4, php 8.1.29, and MariaDB 11.4.3. I can successfully send a test email from the Joomla Administrator MailJet Component Settings. But, selecting 'Contacts' results in a 'Class "Factory" not found' error. The following backtrace is generated in the log:

I'd submit the potential change through Github but I'm a dinosaur - I stopped doing commercial development before git was in use. I think we were using cvs back then. Anyway, I'm looking into git. If I find that I'm looking at more code then I originally intended (not with MailJet, a different app) then I'll make a point of learning git and start contributing.
