  • Hi,

    Can you please tell us what triggered this exception? What did you do to get to this? Some context when this happens would be nice.

    Kind regards,

    Eric.
  • Hello Prof Hverbeek,

    Thank you for your reply.

    I created a plugin which returns a table that contains log relations and their status. 

    When I do run I got these messages of Exception.

    Best regards,

    Rbigui.

  • Hi Rbigui,

    Unfortunately, this is far from sufficient. Basically, we need to be able to replay what you did to check the actual problem. At least we should know what the plug-in is actually doing. Would it be possible for us to have a look at the sources of your plug-in?

    Can it be that your plug-in just returns null instead of a table?

    Cheers,

    Eric.
