I keep getting errors trying to do this, need to query a user property, my settings are all fine, but if I try to execute it from within an app step, the workflow errors out.

I have granted the following permissions to Nintex Workflow

<AppPermissionRequests>

<AppPermissionRequest Scope="http://sharepoint/content/sitecollection" Right="FullControl" />

<AppPermissionRequest Scope="http://sharepoint/social/tenant" Right="Read" />
