Error when sending emails

[privsec]

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

@staff any ideas?

I am afraid you probably have to reach out to the mautic community for such internal issues

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

So I'm still having this issue and am wanting to have it solved.

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

Can you tell us how to reproduce this on a fresh install? If you can set it up on the demo instance (https://my.demo.cloudron.io username/password cloudron), that will help debug the situation.

Thats the issue, I cant replicate it with a fresh install.
