Mention replies on discussions are sending notifications to user 1


This behavior has been resolved and deployed to the production environment as of 2/28/24.


When replying to a discussion reply 4 or more levels deep using Discussions/Announcements Redesign, it automatically @ mentions the user you are replying to, however, the user id autopopulated is user 1, and when you post the reply, it sends a notification to user 1 on the instance.

Expected Behavior

The correct user ID should be populated with the notification going to the correct user.


No workaround exists at this time.

Steps to Reproduce

  • Prerequisite: User with a canvas ID of 1, a published course with 2 users, and Discussions/Announcements Redesign enabled.

  1. Create a published discussion in the course with threaded replies enabled.

  2. As user A, post a reply, then as user B reply to user A. Go back and forth until you are at least 4 threaded replies deep.

  3. Notice that on the 4th level deep, it automatically @ mentions the previous user, and if you check the HTML, it shows: data-mention="1", where the 1 is the user ID that will receive the mention notification.
