Creating AD users trough Powershell activity in UiPath

Question

 i am trying to create AD users with Invoke Powershell activity.

Unfortunately I am stuck with a Parameter problem.

The parameter “Name” gives following error: “The Object name has bad syntax”

The funny thing is, if I run the same powershell command directly into powershell console, I get no error. But when the robot runs it. I get parameter error.

See screenshots for clarification.

I really hope someone can crack this code, because I am pretty stuck here.
