Cause 

The Temporary directory for XML Publisher has not been modified after making the clone so it was pointing to non existing location and getting error out.

Solution

1. Create a new Temporary Directory on OS level for the cloned environment.
2. Make sure that the application owner (APPLMGR) has Read and Write permission this directory.
3. Setup this new directory for XML Publisher via : XML Publisher Administrator responsibility: Properties -> General -> Temporary Directory.
3. Restart the Server.
4. Test again with a XML Publisher Report.
