Problem

In case of admin login (not websudo) If there is a system alert for  Integrity checks and we try to close the alert it throws "HTTP 404 Not Found" HAR attached.

Environment

Bitbucket 9.4.3

Steps to Reproduce

Prerequisite : The environment should have a system alert for Integrity checks

1. Login to Bitbucket with admin access (not webpsudo)
2. click on system alerts
3. click the "X" icon to close/acknowledge the alert
4. We get a Page not found error.

Expected Results

If it is the only system alert then we should see a tick with the below screen or if there are other alerts it should remove the alert from the list without 404 error.

Actual Results

Page not found Error as attached.

Workaround

Login with webspsudo while closing/acknowledging the alert
