Crystal Report using Operational REP Error Message: No PDF report returned from Crystal Web Service

Sorry, this was already logged but closed in error after getting an answer on enabling the Crystal Web Service Logs.

I have the same crystal report in 2 IFS instances.  One works without any issues where as the second on fails with the No PDF report returned from Crystal Web Service.

On checking the log file I get the following:

All other Crystal Reports work in both environments.
