Web interface not accessible for one user (admin)

[dabesa]

Dear support,

The admin user is getting error:

In Lavarel logs I found this:

[2024-03-04 14:37:23] production.ERROR: preg_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated (View: /home/123/helpdesk.123.45/resources/views/users/partials/web_notifications.blade.php) (View: /home/123/helpdesk.123.45/resources/views/users/partials/web_notifications.blade.php) (View: /home/123/helpdesk.123.45/resources/views/users/partials/web_notifications.blade.php) {"userId":1,"email":"@gmail.com","exception":"[object] (ErrorException(code: 0): preg_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated (View: /home/123/helpdesk.123.45/resources/views/users/partials/web_notifications.blade.php) (View: /home/123/helpdesk.123.45/resources/views/users/partials/web_notifications.blade.php) (View: /home/123/helpdesk.123.45/resources/views/users/partials/web_notifications.blade.php) at /home/123/helpdesk.123.45/app/Misc/Helper.php:524, ErrorException(code: 0): preg_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated (View: /home/123/helpdesk.123.45/resources/views/users/partials/web_notifications.blade.php) (View: /home/123/helpdesk.123.45/resources/views/users/partials/web_notifications.blade.php) at /home/123/helpdesk.123.45/app/Misc/Helper.php:524, ErrorException(code: 0): preg_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated (View: /home/123/helpdesk.123.45/resources/views/users/partials/web_notifications.blade.php) at /home/123/helpdesk.123.45/app/Misc/Helper.php:524, ErrorException(code: 0): preg_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated at /home/123/helpdesk.123.45/app/Misc/Helper.php:524)
[stacktrace]

It was working this morning, there was no update or change in the system/settings that I'm aware of.

How to troubleshoot this?

PHP version: 8.1
FreeScout version: 1.8.122
Database: MySQL
Are you using CloudFlare: No

Thanks

The problem was generated by an entry in the "notifications" table.
I searched for all entries for user ID = 1 and deleted the latest ones.

I guess there's a bug with a validation missing for the [object] in the notifications, but I don´t see any unusual subject in the conversation list of that user.

Can I help finding the bug?

Thanks

Fixed in the master branch and will be published in the next release.
