# What this PR does
Email tasks are failing and retrying when they use the fallback default
notification policy as it does not get saved in the DB. This PR uses the
same way as UserNotificationPolicyLogRecord to set that field to null to
avoid `ValueError("save() prohibited to prevent data loss due to unsaved
related object 'notification_policy'.").` when that is the case.
