Pentaho Reporting file output - error: Caught Kettle Exception: Check your configurat

I have a report with a transformation imported into the report from which my data connections to several flat files are established. I am able to execute and the run the report from PRD without issue. However, when trying to initiate the report from PDI vi the Pentaho Reporting file output step I am getting the following error:
