AIF Alerts namespace issue

Hello,

I have configured alerts for Inbound proxy message interface in AIF.

When I test my scenario for failures I do not receive any alerts.

Instead, I get following namespace error though I have defined the recipients in the namespace.

Recipient list ALL (namespace ) cannot be determined

Message no. /AIF/ALERT002

Diagnosis

Recipients are not defined in the given namespace.

Thanks!
