    Default Error with data source PDI

    Hi all,

    I have created a transformation in PDI ( which provides me the results as wanted.
    Next step is to provide this data into a report with Designer (PRD
    Starting the report design wizard I add new data source and choose Pentaho Data Integration.
    I add a name and select the saved transformation.ktr.
    Here I select JSON input and hit preview, this gives me the following error message:

    rg.pentaho.reporting.engine.classic.core.ReportDataFactoryException: Caught Kettle Exception: Check your configuration

    I am using MacOS Sierra 10.12.6.
    I don't see anything in the log file in Kettle and I cannot find a log file in designer.
    I have searched on this forum but nothing really simular.

    Can something explain me this error message?

    Thank you!

    I tried the same with an older version of the reporting tool (
    This does not have this issue.

    So it's a bug in the latest version PRD
