How to get a correct sweep feature?

Hi to all! I´m Pepe from Spain, this is my first post. I am new to PTC Creo and i´ve a problem that i can solve. When I try to sweep a profile for a 3d curved trajectory, I get the mesasage "Feature failed to regenerate" and the reason for Creo is that the geometry is overlapping, I have a correct feature only when the profile is very small...(I want to sweep a 4x5'5mm profile for the blue profile of the attached image)
Thanks in advance and sorry for my english

For a continuous sweep feature, you must not have any sharp corners or edges.

Try after providing corner radius to all sharp corners, as I can see there are 4 of it.
