<![CDATA[Error while selecting mailing list at the email event handler]]>Hi All,

We created a mailing list and an email event handler. Then we selected the mailing list on the email event handler and getting an error as below.

When email address or Mango user is added to email event handler, we can save succesfully.

What could be the reason?

Mango version: v4.0.0.beta7
7fb7d16a-27e7-4277-9011-5a48cf26a442-image.png

Thanks,
