Is there a reason of why wouldnt I be able to do a

Hello, I've been experimenting with non rigid structural dimensioning of certain pieces in my work and recently made this sketch which would be the profile of a mask.

The problem is that when trying to sweep boss the sketch, the error "Sweep operation failed to complete" pops on the event handler.

Would there be any explainable reason of why is the bossing not possible?
I suspect is due zero thickness geometry would be made when the sweep follows the curvature of the spline and that why I'm getting this error, but I'm not sure as I don't have enough experience when working with sweep extrusions.

Here you can see the profile of the piece I want to sweep. mask profile

Here you can the path I wish the profile to follow.

Attached you will find the part file.

Thanks in advance for you help and tips.
