Email feature not working from Cognos Parameterized URL

[Arghya]

Hello All,

We are trying to invoke email containing report output from parameterized URL using Cognos 10.2.2

?b_action=cognosViewer&ui.action=email

However we are getting the error as below :

java.lang.NullPointerException
   at com.cognos.viewer.action.EmailAction.getEmailOptionsMarshaller(Unknown Source)
   at com.cognos.viewer.action.EmailAction.prepareRequest(Unknown Source)
   at com.cognos.viewer.action.CognosViewerAction.execute(Unknown Source)
   at com.cognos.viewer.controller.CognosViewerDispatcherHandler.handleRequest(Unknown Source)

Is there any further change needed at parameterized URL level?

Thanks in advance,
Arghya
