I have run the test script on todays alpha, and am getting the error regarding the start point for nurbs curve. I have then run the test script on this pull request and the error is gone, and the points are available, so I'm happy for this pull request from the hack session to be deployed.

@BHoMBot this is a DevOps instruction. I am requesting neutral checks on: null-handling, documentation-compliance
