Sweep with a closed curve rail

Hello everyone,

I am trying to do a sweep with a closed curve, but its failling. I saw some poosts and tried reparametrizing the rail curve seam but still not working. Anyone know what is happening?

You have to put your section curve exactly where your rail curve starts/ends, and that point should be G1 continuous (don’t put your section in a corner of your rail curve).
