2021.R5(S1): Type 1 Auto-Notify- Transfer Decline 'Failed to send Notification email'

Description
Configured a Transfer Notification of Type = Transfer Decline which is a Type 1 notification and the notification failed to send with the following audit message: Failed to send notification email. Notice Type : TransferDecline

Setup
SELECT *
FROM tbAutoNotification
WHERE NoticeType like '%TransferDecline%'

Audit
SELECT *
FROM tbAuditlog
where AuditType = 'Auto Notification' and AuditLogID = 127213

I based all type 1 notifications working on the fact that Transfer Sent worked, but Transfer Decline did not work.

Environment
Store: St. Johns EntityId = 902 (No Store Culture i.e. Equals Blank)

(1) Steps
1. Create a transfer from Test Store to St. Johns
2. Change Store to St. John's and reject the Transfer from the Test Store

Expected: Default Auto-notification

Results:
Error function: EmailAutoNotificationByNoticeType
Failed to send notification email. Notice Type : TransferDecline
