Error message

A notification setting with the same destination and configuration already exists.

Common causes

• You're creating or updating a notification setting with the same destination (URL or email) and configuration as one that already exists.

Troubleshooting

• Change the destination or configuration so it doesn't match an existing notification setting.
• Check your existing notification settings — if one already covers this, update it instead of creating a new one.
