    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,

    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,

    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?
