CBMA Alerts not working - Consumer queue is not available

Hello,

I am trying a scenario where I can Retrieve Alerts using AlertAPI.

Steps followed from  Michal's blog -

Michal's PI tips: Component based message alerting - API

The Register Consumer worked through WS navigator using the API.  The new consumer is registered and Alert Rules are active.

However, not able to retrieve any alerts using operation RetrieveSingleAlerts. The Response I get through WS navigator is  -

<StatusDetails>Consumer queue is not available: <TEST></StatusDetails>

I have failed the scenario by giving wrong credentials so as to generate the alerts.

Any pointers useful!

Thanks!
