Can not get migrationtools to Run

[Rocketmars]

Im trying to migrate Workitems form one Team to an other. When I start a run i get the error with (Unhandled exception!) Contact the admin. Can not see any statuscode or something.

I used this config. There where XXX is a replacement. Is there a hint how can i make them work?
