Entity.Assign("User"); throwing error

Hi All,

I am writing automation test scripts for CRM using EasyRepro. But for method xrmApp.Entity.Assign("User") it is throwing following error.

Error:

Test method DynamicsCRMTesting.Company.AssignCompany threw exception  System.InvalidOperationException: Me/UserTeam toggle button unavailable

The Assign popup opened and has ME/User Team toggle but still it is throwing error.
