Any way to pull error info from opFillet?

I'm writing an FS that fillets all non-smooth edges normal to a face. I'd prefer to do one fillet op, but sometimes it fails due to fillet overlap. My script will then go to individual fillets and works, but is much slower. In the fillet feature, it throws an error and debug colors the bad geometry. Can I get the same error data from opFillet within my FS? Maybe with a catch block or something?
