I got an identical error in an entirely different workflow. (The entire stack is surprisingly identical, including Bentley.Civil.CadSystem.Microstation.?A0xec45a7bb.inqmn_PointFilterFunction.) This time I was manually setting up a superelevation point control (not using the usual superelevation application button).
The first prompt for a point is simply "Locate Point", not "Locate Pivot Point" or "Locate Reference Point" some such. So I selected the wrong edge of pavement. Then when the other prompt came up, I selected the same point and I just figured I'd fix it later. It never got there, as this exception came up.
Other than the identical stack, though, how I got these exceptions was an entirely different process.
