<![CDATA[Error when sending emails]]>I have email configured correctly and test emails work just fine.

However, when I go into an email I create in mautic and click on Send example I get an error message

In the logs, I get this message

If you can set it up on the demo instance (https://my.demo.cloudron.io username/password cloudron), that will help debug the situation.

Before I reach out to their developers, is there anything we can check or review? ?

Jun 14 19:12:03 [Sat Jun 15 01:12:03.571866 2024] [php:warn] [pid 436] [client 172.18.0.1:56436] PHP Warning: Undefined array key 1 in /app/code/app/bundles/EmailBundle/Helper/MailHelper.php on line 1818, referer: https://mautic.domain.com/s/emails/view/2

This does seem like some internal mautic code issue ("Undefined array key"). Which version of mautic is this? Atleast, it works here.
