Mitering failed at a kink in the rail curve

I’m following your this titrial to make cornices and baseboards but I encounter this error :
Mitering failed at a kink in the rail curve. Try Untrimmed Miters

I have a small notice, in the tutorial she make a sweep for 3 edges, I need to sweep closed curve conrices.3dm (918.1 KB)

Hello - place the section curve somewhere on the straight part of the sweep path, rather than on a corner where it conflicts with the miter.

Does that help?
