Attachements version 4.2.0 Joomla 4.4.14

When I try to add an attachment to an article, I get this error. Is it related to the Helix Framework plugin and template? I have the latest version of PHP 8.1.10

How can I fix this? I won't disable the template add-on because it won't work either.

If you disable the attachments extension and create an article does it still errors out? The backtrace doesn't contain any attachments extension code. As it is right now the issue appear to be on the system plugin Helix Ultimate. Maybe they added typing and broke joomla 4?

I've already written to them, and articles without attachments are created without a problem. I'll see if I have an older version of Helix Ultimate and install it. The Helix update was in early December.

@bsylwek I think I know what is causing the issue. We emit the event with null as value for the isNew variable. I will have to test it a bit but it could be an easy fix.

@bsylwek can you please test the changes I made?

Unfortunately, I don't have FTP access where I am right now. I'll check these fixes tomorrow evening and let you know.

@bsylwek If you do not have an ftp access you can install this version of component to test

attachments_component.PR173.zip

Sorry I haven't written, but I've been away for a while. I've made your corrections and the error isn't recurring. I'll keep monitoring. If anything changes, I'll let you know.
