Crash with BRepFilletAPI_MakeFillet

Hi guys ,I tried to make fillet for curve edges of a STEP file .But it fails to create fillet. I have attached STEP file and the image of one of the curve edge that I tried to make fillet with this post. Is there something wrong in my STEP file or is it an error of makefillet function?. Any help appreciated.

Many thanks in advance!

I'm working on the same subject as you aka turbomachinery and openCascade.
Maybe we could exchange on many subject.
I leave you my mail if you want to contact me directly.

Regarding your compressor blade what is the value of the fillet you want to apply?
