MovieDB is an online app that allows users to explore movies, submit ratings, and share reviews. The actor follow and notification feature keeps users informed when new movies featuring their favorite actors are launched. Currently, this system is not working as expected and your task is to fix the backend for it.

Problem

The actor follow and notification feature keeps users informed when new movies featuring their favorite actors are launched. Currently, this system is not working as expected.

Issue Summary:

When users follow an actor, they should receive a notification whenever a new movie featuring that actor is launched on the app. Currently, users are not receiving these notifications. In addition, the notification number displayed is incorrect, showing unread notifications that do not exist when clicked.

Steps to Reproduce:

• Log in using the following user credentials: Email: sam.river@email.com Password: Password@123
• Click on the user profile present in the navbar and select Follow Actors.
• One or more actors to receive updates when their new movies are added.
• Log out as the user and log in as an admin using the following credentials: Email: admin@moviedb.com Password: Admin@123
• Click on the Admin in the navbar and select Add movie.
• Click on the Admin in the navbar and select Add movie.
• Launch an upcoming movie or add a new movie manually that features one of the following actors.
• Log out as Admin and log back in as the user.
• The user should receive a notification, but there are no new notifications.

Expected Behavior:

• When a new movie featuring a followed actor is launched, the user should receive a notification.
• The bell icon should display the correct count of unread notifications.
• Clicking the bell icon should show the list of notifications.
• Once a notification is viewed, the bell icon count should update accordingly.
