# Problem: AWS::CodeStarNotifications::NotificationRule fails to create during deployment
<a name="problem-notification-rule-fails-to-exist-error"></a>

When deploying a solution that uses the `AWS::CodeStarNotifications::NotificationRule` resource, the resource creation may fail with the error "Invalid request provided: AWS::CodeStarNotifications::NotificationRule". The `AWS::CodeStarNotifications::NotificationRule` resource is attempting to create a notification rule, but the necessary service role has not been fully created yet. This is due to a timing issue, where the resource is trying to create the rule before the service role is ready.

## Resolution

If you encounter this issue, you can try manually retrying the failed resource creation. After approximately 15 minutes, the service role should be fully created, and the `AWS::CodeStarNotifications::NotificationRule` resource should be able to create the notification rule successfully.
