Summary

Project Settings 'Notifications' screen fails to load.

Environment

Jira Cloud

Diagnosis

When attempting to access the Project Settings >> 'Notifications' screen, the page does not load and remains a blank white screen.

Cause

This is caused by a bad record in the Project's assigned Notification Scheme. In most cases the record will appear as an open/close parenthesis with no value "()".

Causes for the null value can vary. Possibly, either the user or group was removed, the value is no longer in the system, or a bad value was migrated into the site. 

Solution

Deleting the NULL value record and refreshing the 'Notifications' page under Project Settings should address the issue.
