Report output to email

Hi All,

As per my requirement, when I do the modifications to the shipment, the shipment report output should send to email in pdf format.
Pre requisites:
1. Report is working fine and set the default mode as pdf in the report definition.
2. SMTP settings done. When do the schedule report and if i give my email id, then i am getting the report output in pdf form to my email.
3. I created a report set also.
4. I created two agents, one with shipment modified event and gave action as PRINT DOCUMENT and attached above report set to that. And second with Report Ready and notify action.

But when I do the modifications to the shipment, agent triggered successfully. But I have not received the report output. In the logs, I could see below error message.

cause.Temp_File_Cache_Error (directory=/u01/OTMAPP/otmapp/otm632/temp)
java.io.IOException: No such file or directory

Need your inputs on this. Please suggest.

Thank you.
