Solution: Correcting Variable Reference

The problem in the toArray() method is that you are trying to access $message directly which is not defined within its scope.

Here’s the Corrected Method

Replace your existing toArray() function with the following corrected code:

Always ensure to check your variable scopes and references, especially when dealing with classes and properties. With this change, your notification system should work flawlessly, keeping users informed about the latest messages in their conversations.
